Effects of deficiency in the RLBP1-encoded visual cycle protein CRALBP on visual dysfunction in humans and mice [Cell Biology]

Mutations in retinaldehyde-binding protein 1 (RLBP1), encoding the visual cycle protein cellular retinaldehyde-binding protein (CRALBP), cause an autosomal recessive form of retinal degeneration. By binding to 11-cis-retinoid, CRALBP augments the isomerase activity of retinoid isomerohydrolase RPE65 (RPE65) and facilitates 11-cis-retinol oxidation to 11-cis-retinal. CRALBP also maintains the 11-cis configuration and protects against unwanted retinaldehyde activity. Studying a sibling pair that is compound heterozygous for mutations in RLBP1/CRALBP, here we expand the phenotype of affected individuals, elucidate a previously unreported phenotype in RLBP1/CRALBP carriers, and demonstrate consistencies between the affected individuals and Rlbp1/Cralbp−/− mice. In the RLBP1/CRALBP-affected individuals, nonrecordable rod-specific electroretinogram traces were recovered after prolonged dark adaptation. In ultrawide-field fundus images, we observed radially arranged puncta typical of RLBP1/CRALBP-associated disease. Spectral domain-optical coherence tomography (SD-OCT) revealed hyperreflective aberrations within photoreceptor-associated bands. In short-wavelength fundus autofluorescence (SW-AF) images, speckled hyperautofluorescence and mottling indicated macular involvement. In both the affected individuals and their asymptomatic carrier parents, reduced SW-AF intensities, measured as quantitative fundus autofluorescence (qAF), indicated chronic impairment in 11-cis-retinal availability and provided information on mutation severity. Hypertransmission of the SD-OCT signal into the choroid together with decreased near-infrared autofluorescence (NIR-AF) provided evidence for retinal pigment epithelial cell (RPE) involvement. In Rlbp1/Cralbp−/− mice, reduced 11-cis-retinal levels, qAF and NIR-AF intensities, and photoreceptor loss were consistent with the clinical presentation of the affected siblings. These findings indicate that RLBP1 mutations are associated with progressive disease involving RPE atrophy and photoreceptor cell degeneration. In asymptomatic carriers, qAF disclosed previously undetected visual cycle deficiency.

{alpha}-Synuclein filaments from transgenic mouse and human synucleinopathy-containing brains are maȷor seed-competent species [Molecular Bases of Disease]

Assembled α-synuclein in nerve cells and glial cells is the defining pathological feature of neurodegenerative diseases called synucleinopathies. Seeds of α-synuclein can induce the assembly of monomeric protein. Here, we used sucrose gradient centrifugation and transiently transfected HEK 293T cells to identify the species of α-synuclein from the brains of homozygous, symptomatic mice transgenic for human mutant A53T α-synuclein (line M83) that seed aggregation. The most potent fractions contained Sarkosyl-insoluble assemblies enriched in filaments. We also analyzed six cases of idiopathic Parkinson's disease (PD), one case of familial PD, and six cases of multiple system atrophy (MSA) for their ability to induce α-synuclein aggregation. The MSA samples were more potent than those of idiopathic PD in seeding aggregation. We found that following sucrose gradient centrifugation, the most seed-competent fractions from PD and MSA brains are those that contain Sarkosyl-insoluble α-synuclein. The fractions differed between PD and MSA, consistent with the presence of distinct conformers of assembled α-synuclein in these different samples. We conclude that α-synuclein filaments are the main driving force for amplification and propagation of pathology in synucleinopathies.

Non-photopic and photopic visual cycles differentially regulate immediate, early, and late phases of cone photoreceptor-mediated vision [Molecular Bases of Disease]

Cone photoreceptors in the retina enable vision over a wide range of light intensities. However, the processes enabling cone vision in bright light (i.e. photopic vision) are not adequately understood. Chromophore regeneration of cone photopigments may require the retinal pigment epithelium (RPE) and/or retinal Müller glia. In the RPE, isomerization of all-trans-retinyl esters to 11-cis-retinol is mediated by the retinoid isomerohydrolase Rpe65. A putative alternative retinoid isomerase, dihydroceramide desaturase-1 (DES1), is expressed in RPE and Müller cells. The retinol-isomerase activities of Rpe65 and Des1 are inhibited by emixustat and fenretinide, respectively. Here, we tested the effects of these visual cycle inhibitors on immediate, early, and late phases of cone photopic vision. In zebrafish larvae raised under cyclic light conditions, fenretinide impaired late cone photopic vision, while the emixustat-treated zebrafish unexpectedly had normal vision. In contrast, emixustat-treated larvae raised under extensive dark-adaptation displayed significantly attenuated immediate photopic vision concomitant with significantly reduced 11-cis-retinaldehyde (11cRAL). Following 30 min of light, early photopic vision was recovered, despite 11cRAL levels remaining significantly reduced. Defects in immediate cone photopic vision were rescued in emixustat- or fenretinide-treated larvae following exogenous 9-cis-retinaldehyde supplementation. Genetic knockout of Des1 (degs1) or retinaldehyde-binding protein 1b (rlbp1b) did not eliminate photopic vision in zebrafish. Our findings define molecular and temporal requirements of the nonphotopic or photopic visual cycles for mediating vision in bright light.

Pro-515 of the dynamin-like GTPase MxB contributes to HIV-1 inhibition by regulating MxB oligomerization and binding to HIV-1 capsid [Microbiology]

Interferon-regulated myxovirus resistance protein B (MxB) is an interferon-induced GTPase belonging to the dynamin superfamily. It inhibits infection with a wide range of different viruses, including HIV-1, by impairing viral DNA entry into the nucleus. Unlike the related antiviral GTPase MxA, MxB possesses an N-terminal region that contains a nuclear localization signal and is crucial for inhibiting HIV-1. Because MxB previously has been shown to reside in both the nuclear envelope and the cytoplasm, here we used bioinformatics and biochemical approaches to identify a nuclear export signal (NES) responsible for MxB's cytoplasmic location. Using the online computational tool LocNES (Locating Nuclear Export Signals or NESs), we identified five putative NES candidates in MxB and investigated whether their deletion caused nuclear localization of MxB. Our results revealed that none of the five deletion variants relocates to the nucleus, suggesting that these five predicted NES sequences do not confer NES activity. Interestingly, deletion of one sequence, encompassing amino acids 505–527, abrogated the anti-HIV-1 activity of MxB. Further mutation experiments disclosed that amino acids 515–519, and Pro-515 in particular, regulate MxB oligomerization and its binding to HIV-1 capsid, thereby playing an important role in MxB-mediated restriction of HIV-1 infection. In summary, our results indicate that none of the five predicted NES sequences in MxB appears to be required for its nuclear export. Our findings also reveal several residues in MxB, including Pro-515, critical for its oligomerization and anti-HIV-1 function.

A neuroglobin-based high-affinity ligand trap reverses carbon monoxide-induced mitochondrial poisoning [Molecular Biophysics]

Carbon monoxide (CO) remains the most common cause of human poisoning. The consequences of CO poisoning include cardiac dysfunction, brain injury, and death. CO causes toxicity by binding to hemoglobin and by inhibiting mitochondrial cytochrome c oxidase (CcO), thereby decreasing oxygen delivery and inhibiting oxidative phosphorylation. We have recently developed a CO antidote based on human neuroglobin (Ngb-H64Q-CCC). This molecule enhances clearance of CO from red blood cells in vitro and in vivo. Herein, we tested whether Ngb-H64Q-CCC can also scavenge CO from CcO and attenuate CO-induced inhibition of mitochondrial respiration. Heart tissue from mice exposed to 3% CO exhibited a 42 ± 19% reduction in tissue respiration rate and a 33 ± 38% reduction in CcO activity compared with unexposed mice. Intravenous infusion of Ngb-H64Q-CCC restored respiration rates to that of control mice correlating with higher electron transport chain CcO activity in Ngb-H64Q-CCC–treated compared with PBS-treated, CO-poisoned mice. Further, using a Clark-type oxygen electrode, we measured isolated rat liver mitochondrial respiration in the presence and absence of saturating solutions of CO (160 μm) and nitric oxide (100 μm). Both CO and NO inhibited respiration, and treatment with Ngb-H64Q-CCC (100 and 50 μm, respectively) significantly reversed this inhibition. These results suggest that Ngb-H64Q-CCC mitigates CO toxicity by scavenging CO from carboxyhemoglobin, improving systemic oxygen delivery and reversing the inhibitory effects of CO on mitochondria. We conclude that Ngb-H64Q-CCC or other CO scavengers demonstrate potential as antidotes that reverse the clinical and molecular effects of CO poisoning.

Reactive dicarbonyl compounds cause Calcitonin Gene-Related Peptide release and synergize with inflammatory conditions in mouse skin and peritoneum [Molecular Bases of Disease]

The plasmas of diabetic or uremic patients and of those receiving peritoneal dialysis treatment have increased levels of the glucose-derived dicarbonyl metabolites like methylglyoxal (MGO), glyoxal (GO), and 3-deoxyglucosone (3-DG). The elevated dicarbonyl levels can contribute to the development of painful neuropathies. Here, we used stimulated immunoreactive Calcitonin Gene–Related Peptide (iCGRP) release as a measure of nociceptor activation, and we found that each dicarbonyl metabolite induces a concentration-, TRPA1-, and Ca2+-dependent iCGRP release. MGO, GO, and 3-DG were about equally potent in the millimolar range. We hypothesized that another dicarbonyl, 3,4-dideoxyglucosone-3-ene (3,4-DGE), which is present in peritoneal dialysis (PD) solutions after heat sterilization, activates nociceptors. We also showed that at body temperatures 3,4-DGE is formed from 3-DG and that concentrations of 3,4-DGE in the micromolar range effectively induced iCGRP release from isolated murine skin. In a novel preparation of the isolated parietal peritoneum PD fluid or 3,4-DGE alone, at concentrations found in PD solutions, stimulated iCGRP release. We also tested whether inflammatory tissue conditions synergize with dicarbonyls to induce iCGRP release from isolated skin. Application of MGO together with bradykinin or prostaglandin E2 resulted in an overadditive effect on iCGRP release, whereas MGO applied at a pH of 5.2 resulted in reduced release, probably due to an MGO-mediated inhibition of transient receptor potential (TRP) V1 receptors. These results indicate that several reactive dicarbonyls activate nociceptors and potentiate inflammatory mediators. Our findings underline the roles of dicarbonyls and TRPA1 receptors in causing pain during diabetes or renal disease.

Brain manganese and the balance between essential roles and neurotoxicity [Molecular Bases of Disease]

Manganese (Mn) is an essential micronutrient required for the normal development of many organs, including the brain. Although its roles as a cofactor in several enzymes and in maintaining optimal physiology are well-known, the overall biological functions of Mn are rather poorly understood. Alterations in body Mn status are associated with altered neuronal physiology and cognition in humans, and either overexposure or (more rarely) insufficiency can cause neurological dysfunction. The resultant balancing act can be viewed as a hormetic U-shaped relationship for biological Mn status and optimal brain health, with changes in the brain leading to physiological effects throughout the body and vice versa. This review discusses Mn homeostasis, biomarkers, molecular mechanisms of cellular transport, and neuropathological changes associated with disruptions of Mn homeostasis, especially in its excess, and identifies gaps in our understanding of the molecular and biochemical mechanisms underlying Mn homeostasis and neurotoxicity.

Inhibition of the polyamine synthesis enzyme ornithine decarboxylase sensitizes triple-negative breast cancer cells to cytotoxic chemotherapy [Molecular Bases of Disease]

Treatment of patients with triple-negative breast cancer (TNBC) is limited by a lack of effective molecular therapies targeting this disease. Recent studies have identified metabolic alterations in cancer cells that can be targeted to improve responses to standard-of-care chemotherapy regimens. Using MDA-MB-468 and SUM-159PT TNBC cells, along with LC-MS/MS and HPLC metabolomics profiling, we found here that exposure of TNBC cells to the cytotoxic chemotherapy drugs cisplatin and doxorubicin alter arginine and polyamine metabolites. This alteration was because of a reduction in the levels and activity of a rate-limiting polyamine biosynthetic enzyme, ornithine decarboxylase (ODC). Using gene silencing and inhibitor treatments, we determined that the reduction in ODC was mediated by its negative regulator antizyme, targeting ODC to the proteasome for degradation. Treatment with the ODC inhibitor difluoromethylornithine (DFMO) sensitized TNBC cells to chemotherapy, but this was not observed in receptor-positive breast cancer cells. Moreover, TNBC cell lines had greater sensitivity to single-agent DFMO, and ODC levels were elevated in TNBC patient samples. The alterations in polyamine metabolism in response to chemotherapy, as well as DFMO-induced preferential sensitization of TNBC cells to chemotherapy, reported here suggest that ODC may be a targetable metabolic vulnerability in TNBC.

Five Lessons From the New Arab Uprisings

12 November 2019

Dr Georges Fahmi

Associate Fellow, Middle East and North Africa Programme
Georges Fahmi examines how protesters across the region have adapted their tactics after the experiences of the Arab Spring.

The second wave of Arab uprisings that started in Sudan in December last year and extended to Algeria, Lebanon and Iraq this year have built on past experiences of political transitions during the Arab Spring, both its mistakes and achievements. Protesters from this new wave have already learned five lessons from previous transitions.

The first lesson is that toppling the head of a regime does not mean that the political regime has fallen.  In Tahrir Square on 11 February 2011, Egyptian protesters celebrated the decision of Hosni Mubarak to step down and left the square, thinking his resignation was enough to allow a democratic transition to take place. In contrast, in Sudan and Algeria, protesters continued to demonstrate after the resignation of Abdelaziz Bouteflika and the military-led ousting of Omar al-Bashir.

Protesters understood the lesson that the regime is found not only in the head of the state, but rather in the rules that govern the political sphere. By extension, political change requires changing the rules, not just the names of those in charge of implementing them.

The second lesson is that resorting to violence is the fastest way to end any hope for democratic change. Protesters who decided to take up arms offered their regimes the chance to reframe the political uprisings as civil war, as was the case in Syria. Even when armed groups manage to bring down the regime, their presence endangers the transitional phase afterwards, as is the case in Libya.

Although protesters in Sudan and Iraq have been faced with government violence and repression, they have insisted on their non-violent approach. In Sudan, the protesters responded to the massacre outside of the General Command of the Armed Forces on 3 June by organizing a mass demonstration on 30 June, which put pressure on the military to resume talks with the revolutionary forces.

The third lesson is that once the old regime has fallen, the transition period must be a collective decision-making process in which the opposition has, at least, veto power. The example of Tunisia after 2011 is a case in point. The Higher Authority for Realization of the Goals of the Revolution, Political Reform and Democratic Transition, which formulated the planned course of the transition, included representatives from across the political spectrum and civil society.

Although the military forces in Algeria and Sudan will not cease to play a political role any time soon, this does not have to mean exerting complete control over the transitional period. Sudan could offer a positive example in this regard, if it succeeds in implementing a power-sharing deal according to which a joint civilian-military sovereign council will govern Sudan during the transitional period.

The fourth lesson is that political transitions should achieve agreement on the rules of the game before proceeding to elections. In Egypt after 2011, rushed elections served to divide the political opposition and dramatically increase polarization in society. In this second wave, protesters have perceived elections as a trap which enable old regimes to reproduce themselves with new names.

In both Algeria and Sudan, protesters have resisted attempts by the military to hold elections as soon as possible. In Sudan, the agreement between the revolutionary forces and the military council postponed the elections until after the end of a three-year transitional period of technocratic rule. In Algeria, protesters are taking to the streets every Friday to demonstrate against the authorities’ decision to hold presidential elections in December.

The fifth and final lesson is that the call for change in the region goes beyond electoral democracy and extends to deep socioeconomic reforms. Iraq and Lebanon show this clearly: relatively free and fair elections have already been held but have served only to reinforce corrupt sectarian regimes.

According to the fifth wave of the Arab Barometer, the economic situation and corruption are perceived as the main challenge for Algerians (62.2%), Sudanese (67.8%), Lebanese (57.9%), and Iraqis (50.2%), while democracy is perceived as the main challenge for only 2.3%, 3.9%, 5% and 1.4% respectively.  The experience of the Arab Spring has shown people that democratic measures are only a means to an end.

Unlike in 2011, when the Arab Spring revolts enjoyed broad international support, this second wave is taking place in a hostile environment, with stronger Russian and Iranian presences in the region and an indifferent international climate. But where protesters have the advantage is in experience, and across the region they are clearly adapting their tactics to lessons learned from the early part of the decade.

Report Launch – Owners of the Republic: An Anatomy of Egypt's Military Economy

Research Event

12 December 2019 - 5:30pm to 6:30pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Yezid Sayigh, Senior Fellow, Carnegie Middle East Center
David Butter, Associate Fellow, Middle East and North Africa Programme, Chatham House
Chair: Lina Khatib, Head, Middle East and North Africa Programme, Chatham House

The Egyptian military accounts for far less of the national economy than is commonly believed but transformations in its role and scope since 2013 have turned it into an autonomous economic actor that can reshape markets and influence government policy and investment strategies. Will the military economy contract to its former enclave status if Egypt achieves successful economic growth or has it acquired a permanent stake that it will defend or even expand?

This roundtable will mark the London launch of a Carnegie Middle East Center report on Egypt’s military economy. The report author, Yezid Sayigh, will begin the discussion with remarks on Egypt’s military economy model and offer thoughts on how external actors can engage the country’s formal and informal networks. David Butter will serve as discussant and the roundtable will be moderated by Lina Khatib.

Chair: Lina Khatib, Head, Middle East and North Africa Programme, Chatham House

Over recent weeks, widespread popular protests have engulfed Iraq and Lebanon. What began as calls for reform in the context of high unemployment and endemic corruption have evolved into direct challenges to the existing political order in both countries.

In response, ruling elites have moved to protect the systems from which they draw power. In Iraq, the state has responded to protests with violence, killing more than 300 people and injuring over 15,000. In Lebanon, protesters are facing attempts at co-optation and intransigence by their leaders. These developments have served to underline the widening gap between elites and ordinary citizens and to highlight geopolitical tensions in the region that have contributed to both countries' woes.

This event will delve into what is at stake for those mobilizing in Iraq and Lebanon. Speakers will discuss the obstacles to meaningful reform and possible routes out of the current crises.

Libya Needs an Economic Commission to Exit From Violence

20 November 2019

Tim Eaton

Senior Research Fellow, Middle East and North Africa Programme
A new effort to manage the economy, one that brings together both sides of the war with international partners, is an essential step forward.

There has been a stark contrast between messaging coming from the international community and trends on the ground as Libya’s latest bout of civil war enters its eighth month.

Led by Germany, some states have been trying to build consensus for a ceasefire ahead of a summit that is expected to be held in Berlin in the next few months. Today marks the date of one of the final planning meetings for the summit.

The increasing use of drone technology, airstrikes and further influxes of fighters trend points in the opposite direction. Warring groups in Libya continue to receive support from external states, undermining international efforts to de-escalate the conflict. A UN arms embargo goes largely unenforced. As the Berlin process unfolds, there is little evidence to suggest that these external states will shift their positions.

The launch of Field Marshal Khalifa Haftar’s Libyan Arab Armed Forces (LAAF) offensive on Tripoli in April sunk a UN-planned ‘national conference’, intended to be held less than two weeks later, to negotiate a framework for transition out of Libya’s governance crisis. Yet, Haftar has so far failed in his objective of capturing Tripoli. While his offensive continues, had he the capacity to capture the city, he would have done so already.

This has created a conundrum for peace talks: there appears to be little chance of negotiating a deal with Haftar, while it is also hard to see how a deal could be reached without him.

The field marshal has little interest in accepting a withdrawal, even a partial one, of his forces. His opponents – who have found unity in their shared efforts to defeat Haftar’s forces – will not accept a ceasefire that leaves the LAAF on the hinterlands of the capital. Similarly, a deal apparently agreed in Abu Dhabi between Haftar and Prime Minister Fayez al-Serraj in February is also dead in the water.

Amid this logjam, there has been an increasing interest in the economic content of the Berlin summit. Countries supportive of Haftar argue that his alliance has legitimate concerns over the management of Libya’s economy and, particularly, the dominant role of the Tripoli-based central bank and its governor in supporting armed groups.

For some within these countries, changing the leadership of the central bank and a finding means of limiting the dominance of the UN-backed Government of National Accord (GNA) over the state’s resources – thus reducing flows of funding to armed groups fighting Haftar – could present a point of agreement in Berlin.

But their focus on financial management in Tripoli is not mirrored by interest in holding the rival central bank in the eastern city of Bayda – an institution unrecognized by the international community – to account for its pursuit of its own monetary policy. This is built on approximately $23 billion of unsecured debt from commercial banks and $11 billion of currency supplied by Russia.

Indeed, very few of the conversations surrounding parameters for Berlin contain details of what would be asked of eastern-based actors beyond pursuit of an audit of the Tripoli and Bayda central banks (only the Tripoli bank is recognized by the international community).

Clearly, the GNA and its allies would have no incentive to accept provisions that limit their means to mobilize resources for the war while its opponents do not receive the same scrutiny. 

However, it is possible to capitalize on the broad interest in economic content to reach some points of agreement over the management of the economy and state institutions. Rather than seeking to replace individuals aligned with one faction for those aligned with another, or expecting asymmetrical concessions from the GNA and its allies, this effort must instead focus on structures and processes that exacerbate the conflict and represent major grievances for the warring parties.

Importantly, this would include the establishment of a system of transparency and accountability for the management of Libya’s finances.  The opacity of current processes enables the support of patronage-based networks with no effective oversight.

Linked to this, the development of effective processes for budgeting and allocating funds could help to reduce graft.

And, finally, rationalizing the role of state institutions to agree their roles and responsibilities, creating the room for reforms to Libya’s system of state employment and subsidies through provision of direct payments to Libyan citizens, is essential.  

An economic commission that comprises members from across political and institutional divides – receiving political support from international powers and technical support from international financial institutions – could be an effective approach. Such a commission could match an inclusive, Libyan-led process with international support to progressively harmonize economic and financial policy between rival authorities and develop consensus for a process of institutional reunification in Libya.

This would constitute a major element of an eventual political settlement and reduce the risk of a limited set of actors capturing the system at the expense of the others – an outcome which would likely result in future bouts of violence.

Such a commission would offer a means of addressing a key driver of the conflict by decentralizing aspects of Libya’s governance, moving away from the dominance of Tripoli and the current winner-take-all system. 

These issues cannot be put to one side, to follow progress on the security front. The remarkable resilience that Libya’s economy has shown over the last seven months should not be taken for granted. It has become increasingly difficult for Libya’s institutions to insulate themselves from the conflict as both sides seek to mobilize resources to sustain their war effort.

The LAAF is increasingly looking to sideline civilian authorities in eastern Libya. On the other side, the GNA has found means of routing funds to armed groups fighting Haftar.

In September, a dispute over the supply of jet fuel between the LAAF and the National Oil Corporation resulted in the establishment of a parallel Brega Petroleum Marketing Company, the state-owned company that possesses a monopoly over fuel distribution.

Meanwhile, other major problems lurk under the surface.  The banking sector is in an increasingly perilous state and debts continue to mount all around, with those in the east not accounted for by Tripoli’s official authorities.  

Through the establishment of an economic commission, the Berlin process provides an opportunity and – most importantly – a mechanism to address these problems while also helping to maintain the basic functionality of the state.  Even if a ceasefire deal does not materialize, initiating negotiations about the future shape of the state and its economy would be a significant step forward.

As Parliamentary Elections Loom, the Legitimacy of Iran’s Regime Has Been Shaken

5 December 2019

Dr Sanam Vakil

Deputy Director and Senior Research Fellow, Middle East and North Africa Programme
The latest wave of protests highlights a fracturing social contract in the Islamic Republic.

2019-12-05-Iran.jpg

For four decades, the rule of Iran’s Islamic Republic has rested on the pillars of redistributive social justice, foreign policy independence, Islam and a managed form of electoral legitimacy.  These pillars, each of equal importance, have served as guiding principles bolstering Iran’s domestic and foreign policy decisions.  Amid the latest round of protests to have gripped Iran, it is clear that these pillars are fracturing. 

On 15 November at midnight, the Iranian government, in a move supported by Supreme Leader Ali Khamenei, President Hassan Rouhani, Speaker of the Parliament Ali Larijani and Head of the Judiciary Ebrahim Raisi, announced a 200 per cent increase in fuel prices – a redistributive measure designed to provide cash transfers to the population.

In immediate reaction, Iranian citizens took to the streets to express their discontent with this policy move alongside mounting economic and political grievances.

What ensued over the subsequent days was an outbreak of protests through 100 Iranian cities, including at universities and bazaars, that was followed by a weeklong internet blackout and a brutal crackdown that has left at least 200 people dead and 7,000 arrested. Initially, public anger focused on the price increases but quickly targeted the political leadership, lack of government accountability, effective governance and corruption.

This wave of protests is the fourth in a two-decade period – 1999, 2009, 2017 and 2019 – for the Islamic Republic and comes at time when the Iranian government is under severe economic strain from Washington’s maximum pressure campaign. It is equally burdened by endemic factional politicking.

These protests are one of many reminders of the shattered social contract between state and society in Iran, which without repair will continue to resurface.

With internet connectivity resumed and news of the regime’s brutality spreading, conservatives and reformists are both trying to distance themselves from this internal crisis and reposition themselves in advance of the 2020 parliamentary elections.

Parliamentary elections for Iran’s 290-person legislature are expected to be held on 21 February. Amid concerns over public apathy and lower political participation, both reformists and conservatives are trying to develop strategies to maximize gains at their ballot box.

Even before these protests, voter turnout was anticipated to be lower than normal. Participation in the July 2019 Tehran municipality election was at a nadir of 9 per cent.  To prepare for this challenge, Iran’s parliament has lowered the vote threshold for a valid result from 25 to 20 per cent.

Elections in Iran, while by no means completely free and fair due to the vetting of candidates by the Guardian Council, have repeatedly been an important barometer of public support and participation. Electoral participation, which is traditionally higher than in most Western democracies, and compared to the lack of electoral opportunities in the Middle East, is heralded as a sign of public legitimacy. 

Voter participation is generally higher in presidential elections than in legislative ones.

For example, 73% voted in the 2017 presidential elections, 72% in 2013, 80% in the contested 2009 elections, and 59% in 2005 elections that brought Mahmood Ahmadinejad to office. Comparatively, in the 2016 parliamentary elections 62% voted, in 2012, 66%, in 2008, 47%, and in 2004, 51% participated.

Voter turnout in the 2008 parliamentary elections, reflective of public apathy, mounting international tensions over the nuclear programme, and Guardian Council vetting of reformist candidates, could be emblematic of what to expect next year. 

In the run up to the election, conservative groups are trying to capitalize on popular economic frustrations, disappointment with reformists, wider regional security concerns and tensions with the United States to rally voters. 

Reformists associated with the Rouhani government, who also supported the Iran nuclear agreement, have been severely weakened by the US maximum pressure campaign and the return of US sanctions.  They are also blamed for the current economic downturn and remain frustrated by their ability to affect change in a political system that affords more power to unelected figures.

Amidst this stalemate, Rouhani has continued to call for a national referendum to no avail, while reformist groups are debating how to position themselves – some even calling for greater accountability – so as not be tainted by the government crackdown. Leading reformist politicians such as Mohammad Khatami have called on reformists to stay united and avoid boycotting the elections. It remains to be seen how their strategy will develop after the protests.

Should the Guardian Council bar too many reformists from running, calls for a boycott could snowball and even incite new protests. Together with low turnout at the ballot box, the outcome of this election could further damage the regime’s already fragile electoral pillar and weaken its claims to legitimacy.

Iraq's Reconstruction: In Conversation with Governor of Anbar Ali Farhan Hamid

Invitation Only Research Event

18 December 2019 - 9:00am to 10:30am

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Ali Farhan Hamid, Governor of Anbar Province
Chair: Dr Renad Mansour, Senior Research Fellow, Middle East and North Africa Programme, Chatham House

In the aftermath of the liberation from ISIS, the government of Iraq was left to count the cost of three years of brutal conflict, only the most recent phase in the ongoing cycle of conflict and stabilization that has plagued Iraq for 16 years. While reconstruction has been a focus of both the Iraqi government and international policymakers since 2003, billions of dollars in pledged funds have continually failed to reach the places they are most needed. 

At this roundtable, Ali Farhan Hamid will discuss the efforts of his provincial government to rebuild the cities and towns worst-hit by the conflict. He will provide insights into the practical and structural impediments to reconstruction efforts in both Anbar and neighbouring provinces such as Ninewah where the worst damage was sustained under ISIS but where little in the way of reconstruction has been achieved thereby leaving the door open to the potential resurgence of conflict.

The roundtable is part of the Chatham House Iraq Initiative.

An unexpected bounty for Iran

Sanam Vakil

The assassination of Qassem Soleimani has been an unexpected bounty for the Islamic Republic at a time when Iran was balancing multiple economic, domestic and regional pressures stemming from the Trump administration’s maximum pressure campaign.

Coming on the heels of anti-Iranian demonstrations in Iraq and Lebanon, and following Iran’s own November 2019 protests that resulted in a brutal government crackdown against its own people, the Soleimani killing has helped the Iranian government shift the narrative away from its perceived regional and domestic weaknesses to one of strength.  

The massive funeral scenes in multiple Iranian cities displaying unending waves of mourners chanting against the United States has provided the Islamic Republic with a unique opportunity to showcase its mobilizing potential. This potential is not limited to Iran but also extends to Iraq and Lebanon, where Tehran’s transnational summoning power has also been visible. The Iraqi parliamentary vote to end the American military presence is one early negative consequence. While the region awaits Iran’s response, further anti-American rallying cries will continue to reverberate.  

Domestically, Soleimani’s death and President Donald Trump’s continued provocations on Twitter, including threats to attack 52 Iranian cultural sites, are being used as a nationalist rallying cry. This sentiment should not be seen solely as Islamic or ideological, but rather an opportunity for the state to pivot to an Iranian-based nationalism that is more inclusive and empowering for much of the country’s disgruntled youth.

Iran’s notoriously divided political factions have also unified in the face of this crisis. With parliamentary elections looming in February and turnout previously expected to be low, the political establishment is likely to use this crisis to mobilize voters in favour of conservative candidates.  

How Tehran chooses to respond to Qassem Soleimani’s death will very much determine its ability to continue to control the narrative and manage its swell of domestic and regional support. For these benefits to continue to manifest, it is important for Tehran to balance the mix of public sympathy and international anxiety and not overplay its hand in its quest for revenge.

A reset for Iraqi politics

Renad Mansour

The US strike which killed Qassem Soleimani and Abu Mehdi al-Muhandis has grave implications for Iraq. The act jeopardizes Iraq’s recently stabilized security situation, and threatens to reshape the country’s political environment, moving backwards to the days of anti-Americanism and sect-based mobilization. If Baghdad loses relations with the US and other diplomatic representations, it risks turning into a pariah state. 

Over the past few years, and notably since October 2019, young Iraqis have taken to the streets demanding reform and the downfall of the political establishment, and its main external backer Iran. The political establishment, including political parties and militias close to Tehran, failed to appease or suppress these protests. Now, these political elites are using the deaths of Muhandis and Soleimani to (re)gain popularity from their own population, by drawing on the old tool of anti-Americanism. 

Following the attacks, Shia populist cleric Muqtada al-Sadr – who until recently had called for an end to Iranian and pro-Iranian militia influence in Iraq – has called to revamp the Mehdi Army that he led until 2008 and is calling for ‘Islamic resistance’ to the US. In seeking to regain control of his former movement, he is coming closer to former Shia foes.

For years, pro-Iranian groups attempted to push the US out of Iraq. Their calls often fell on deaf ears, as public opinion in Iraq did not consider the US as a threat and some even supported the US and international effort against ISIS. Following the attacks, however, anti-American voices have gained more ammunition.

A complete American withdrawal would not only have direct security implications but force other countries and organizations, from European states to NATO, to reconsider their positions and role.

Limited options for ‘revenge’ in the Levant

Lina Khatib

Iran’s use of Lebanon and Syria as spaces for revenge against the US is unlikely.

On Sunday, Hezbollah leader Hassan Nasrallah vowed revenge for Soleimani’s death by singling out American soldiers as a target. However, Hezbollah’s options are limited. Lebanon is in the middle of wide-ranging protests against the country’s ruling political class, of which Nasrallah is a key figure.

Unlike in 2006, when Hezbollah’s military actions against Israel rallied the public around it, today there is no public appetite for dragging Lebanon into a war. Were Hezbollah to instigate one, it would incur public anger, if only for the economic repercussions that would exacerbate an already severe financial crisis in Lebanon. Lebanon also does not have any US military bases that could be a target for Hezbollah.

In theory, Hezbollah or other Iranian-backed groups could attack American bases in Syria. But these bases are staffed by multinational forces from the international anti-ISIS coalition. Attacking them would therefore put Iran in confrontation with other countries besides the US, which is not in Iran’s interest.

Attacking US soldiers in northeast Syria would also go against Kurdish interests because it would weaken the anti-ISIS coalition front of which Kurdish forces are part. It would, furthermore, anger Arab tribes in the area, opening up possibilities for ISIS to take advantage of public dissent to stage a comeback. Iran would then find itself fighting on several fronts at once, which it does not have the capacity to handle. 

More likely, Iran’s allies and proxies in the Levant are going to engage in strong rhetoric without taking hasty actions. When a key Hezbollah leader, Imad Mughniyeh, was assassinated in Damascus on 2008, there were strong words and public vows to seek revenge for his killing, but ultimately there was no response.

Oman’s New Sultan Needs to Take Bold Economic Steps

16 January 2020

Associate Fellow, Middle East and North Africa Programme
The country is in a good regional position, but the economy is at a crossroads.

The transition of power in Oman from the deceased Sultan Qaboos to his cousin and the country’s new ruler, Sultan Haitham bin Tariq, has been smooth and quick, but the new sultan will soon find that he has a task in shoring up the country’s economic position.

Above all, the fiscal and debt profile of the country requires careful management. Fiscal discipline was rare for Oman even during the oil price spike of the 2000s. Although oil prices only collapsed in 2014, Oman has been registering a fiscal deficit since 2010, reaching a 20.6 per cent high in 2016. As long as fiscal deficits remain elevated, so will Oman’s need to finance those deficits, predominately by borrowing in the local and international market.

Oman’s Debt-to-GDP ratio has been rising at a worrying pace, from 4.9 per cent in 2014 to an IMF-estimated 59.8 per cent in 2019. By 2024, the IMF is forecasting the ratio to reach nearly 77 per cent. A study by the World Bank found that if the debt-to-GDP ratio in emerging markets exceeds 64 per cent for an extended period, it slows economic growth by as much as 2 per cent each year.

Investors are willing to lend to Oman, but the sultanate is paying for it in terms of higher spreads due to the underlying risk markets are placing on the rising debt profile of the country. For instance, Oman has a higher sovereign debt rating than Bahrain yet markets perceive it to be of higher risk, making it costlier to borrow. Failure to address the fiscal and debt situation also risks creating pressure on the country’s pegged currency.

If oil revenues remain low, Sultan Haitham will have to craft a daring strategy of diversification and private sector growth. He is well placed for this: Sultan Haitham headed Oman’s Vision 2040, which set out the country’s future development plans and aspirations, the first Gulf country to embark on such an assessment. However, like all vision documents in the Gulf, Oman’s challenge will be implementation.

In the age of climate change, renewable energy is a serious economic opportunity, which Oman has to keep pursuing. If cheap electricity is generated it could also be exported to other Gulf states and to south Asia. In Oman, the share of renewables in total electricity capacity was around 0.5 per cent in 2018; the ambition is to reach 10 per cent by 2025.

However, in order to reach this target, Oman would have to take additional measures such as enhancing its regulatory framework, introducing a transparent and gradual energy market pricing policy and integrating all stakeholders, including the private sector, into a wider national strategy.

Mining could provide another economic opportunity for Oman’s diversification efforts, with help from a more robust mining law passed last year. The country has large deposits of metals and industrial minerals and its mountains could have gold, palladium, zinc, rare earths and manganese.

Oman’s strategic location connecting the Gulf and Indian Ocean with east Africa and the Red Sea could also boost the country’s economy. The Duqm special economic zone, which is among the largest in the world, could become the commercial thread between Oman, south Asia and China’s ‘Belt and Road Initiative.’

Oman has taken important steps to make its economy more competitive and conducive to foreign direct investment. Incentives include a five-year renewable tax holiday, subsidized plant facilities and utilities, and custom duties relief on equipment and raw materials for the first 10 years of a firm’s operation in Oman.

A private sector economic model that embraces small- and medium-sized enterprises as well as greater competition and entrepreneurship would help increase opportunities in Oman. Like all other Gulf economies, future employment in Oman will have to be driven be the private sector, as there is little space left to grow the public sector.

Privatization needs to continue. Last year’s successful sale of 49 per cent of the electricity transmission company to China’s State Grid is a very positive step. The electricity distribution company as well as Oman Oil are next in line for some form of partial privatization.

The next decade will require Oman to be even more adept in its competitiveness as the region itself tries to find its new bearings. Take tourism for instance; Oman hopes to double its contribution to GDP from around 3 per cent today to 6 per cent by 2040 and the industry is expected to generate half a million jobs by then. Over the next 20 years, Oman will most likely be facing stiff competition in this area not only by the UAE but by Saudi Arabia as well.

The new sultan has an opportunity to embark on deeper economic reforms that could bring higher growth, employment opportunities and a sustainable future. But he has a big task.

Local Pathways Towards De-escalation of Libya's Conflict

Invitation Only Research Event

Chair: Tim Eaton, Middle East and North Africa Programme, Chatham House

A shaky truce remains broadly in place among rival Libyan forces fighting for control of Tripoli. However, a durable ceasefire to bring an end to the current bout of conflict, which was initiated by Khalifa Haftar’s Libyan Arab Armed Forces’ (LAAF) offensive on the capital in April 2019, has not been reached. In recent weeks attention has focused on talks hosted in Moscow and Berlin, with the former aimed at agreeing a ceasefire and the latter seeking to reach agreement among international actors to bring an end to external military support for Libyan warring actors, and to craft a way forward for future intra-Libyan talks. Yet, there has been little emphasis on Libyan actors – beyond Haftar and prime minister Fayez al-Serraj – in this process.
 
This roundtable will bring together experts and policymakers to discuss means of de-escalating the conflict and seeking a lasting resolution through the development of interconnected intra-Libyan social and security negotiation tracks. Mr Usama Otman Essed of the Libya Center for Strategic and Future Studies (LCSFS) will present his research group’s ideas on these issues and discuss their ongoing efforts to promote dialogue among social and security actors.

Prospects for Reforming Libya’s Economic Governance: Ways Forward

Invitation Only Research Event

6 February 2020 - 10:30am to 12:30pm

Chair: Elham Saudi, Director, Lawyers for Justice Libya

There is a broad consensus that Libya’s rentier, patronage-based system of governance is a driver, and not only a symptom, of Libya’s continuing conflict. The dysfunction of Libya’s economic system of governance has been exacerbated by the governance split that has prevailed since 2014 whereby rival administrations of state institutions have emerged. Despite these challenges, a system of economic interdependence, whereby forces aligned with Field Marshal Haftar control much of the oil and gas infrastructure and the UN-backed Government of National Accord controls the means of financial distribution, has largely prevailed. Yet, at the time of writing, this is under threat: a damaging oil blockade is being implemented by forces aligned with Haftar and those state institutions that do function on a national basis are finding it increasingly difficult to avoid being dragged into the conflict.

This roundtable will bring together analysts and policymakers to discuss these dynamics and look at possible remedies. Jason Pack, non-resident fellow at the Middle East Institute, will present the findings of his latest paper on the issue which recommends the formation of 'a Libyan-requested and Libyan-led International Financial Commission vested with the requisite authorities to completely restructure the economy.' Tim Eaton, who has been leading Chatham House’s work on Libya’s conflict economy, supporting UNSMIL’s efforts in this field, will act as respondent.

Attendance at this event is by invitation only.

Lebanon Is Paying the Cost of Its Dysfunctional Politics

26 February 2020

Associate Fellow, Middle East and North Africa Programme
A series of fights to political stalemate have led its economy to the brink and cut it off from its natural economic partners in the Gulf.

To understand Lebanon’s financial collapse, look to its politics.

The country has been deeply damaged by an increasingly dysfunctional political system. A series of compromises have alienated it from its main markets in the Gulf and strangled its economy; anyone that has glanced at fluctuations in Lebanese bank deposits over the last 10 years can see the correlation.

Imagine if Boris Johnson or Donald Trump were obliged to form joint governments with Jeremy Corbyn or Bernie Sanders. The result would be paralysis and lack of accountability as each party pulls the country in opposite directions and blames the other for the state of limbo. This has been the state of affairs in Lebanon since the Doha agreement of 2008. 

That agreement followed an 18-month siege that paralyzed Beirut and an attack on the city by Hezbollah’s ‘black shirts’. The Doha formula imposed governments of national unity between Prime Minister Saad Hariri’s pro-Saudi camp and Hezbollah’s pro-Iran camp and their respective internal allies.

The pattern was set: each period of subsequent paralysis was followed by further compromise as the tug of war pulled the country away from its principal economic partners, the Arab Gulf states, with the regional balance of power tilting towards Hezbollah. 

It was not supposed to be like this. The Baabda Declaration in June 2012, reached after a process of national dialogue, was meant to secure Lebanon’s neutrality in regional conflicts, with both sides promising to hold back on external alliances and coexist despite difference over major regional issues like the war in Syria, the standoff between the US and Iran or relations with Israel or the Gulf states.

This has worn away. The Baabda declaration itself became a sham when Hezbollah inserted itself into the war in Syria in support of the Assad regime and overtly got involved in Iraq and Yemen as an Iranian proxy. This was followed by Saudi opposition to concessions by Hariri that led to the election of General Michel Aoun, an ally of Hezbollah, as president in October 2016; again, after a political paralysis that lasted 29 months with no active government and no head of state.  

The Saudis were also furious when President Aoun’s son-in-law, Foreign Minister Gebran Bassil, abstained from condemning the burning of the Saudi embassy in Tehran at an Arab League meeting in Cairo in January 2016, citing the need to preserve national unity.

Fearing that he was simply providing Hezbollah with protection in the guise of compromise, the Saudis pressured Hariri to resign in November 2017 during a trip to Riyadh, but he later challenged that by retracting on his resignation when back in Beirut. Lebanon was caught between two sides, and as the regional conflict intensified from tension to open confrontation, neutrality was no longer an option.

Gulf connections

An estimated 350,000 Lebanese expats live and work in Saudi Arabia, the UAE, Qatar and Kuwait. These countries are also the main clients for Lebanese contractors, consultants and advertising companies, some of which have offices there. The domestic tourism industry relies heavily on Arab Gulf visitors and they are a principal source of foreign investments especially in the real estate sector.

Lebanon also enjoyed a certain degree of political and economic protection from the US and the Gulf, and Hezbollah benefited indirectly from that protection, as it also shielded it to a certain degree from sanctions.

The deterioration of relations meant that the country was cut off by its Gulf partners. This was manifested in travel bans for Gulf Cooperation Council (GCC) nationals to Lebanon and a decrease in investments and bank deposits, as well as a decrease in remittances from Lebanese expats, partly because of economic crisis in the Gulf countries themselves.

Saudi Arabia withdrew $4 billion of aid to the Lebanese army and internal security forces, and no aid or deposits were forthcoming as the economic and financial situation deteriorated. 

The costs to the Lebanese economy include the opportunity cost created by the annual threat of war with Israel, after which trips are cancelled and projects postponed. Hezbollah also controls a section of Beirut port where it pays no duty or taxes. Add to that the economic fallout from the war in Syria, such as the impact on exports, the inflow of refugees and the cost of Hezbollah’s involvement.

The burden of these political factors is difficult to estimate but it constitutes the ransom that the Lebanese economy bears as a cost of the compromise. This is not to absolve Lebanese politicians from corruption or bankers of mismanagement but to add that political factors cannot be ignored.

The cumulative cost and economic impact of being cut off from its main economic partner eventually bankrupted the country. The fiscal and financial aspects, with Lebanon’s inability to service its debt, are but a reflection of these political factors. In the long run, the key to avoiding complete collapse is to restore relations with the GCC and free Lebanon from that very costly grip.

Expanding Sino–Maghreb Relations: Morocco and Tunisia

26 February 2020

Over the past two decades, China has increased its presence in North Africa in terms of trade and investment. This paper looks at China’s policy within the context of its Africa and Middle East policies to better understand its approach to Morocco and Tunisia.

Summary

  • China’s presence in the Maghreb has increased in recent years, raising concerns among Western powers. China has focused on bilateral relations with these countries while also working within the Forum on China–Africa Cooperation (FOCAC) and the China–Arab States Cooperation Forum (CASCF). However, this engagement has limited strategic value compared to relations China has with Saudi Arabia or the United Arab Emirates.
  • Since the launch of the Belt and Road Initiative (BRI) in 2013, China has shown greater interest in the Maghreb as an entry point to European and African markets. China has pursued commercial relations over political influence in the region. Morocco and Tunisia are still dependent on France, their former colonial power, and the European Union, which exert great political, economic, security and cultural influence over the two countries.
  • The Maghreb countries’ economic relations with China have grown exponentially, with Algeria forming the closest relationship. However, Morocco and Tunisia are keen to attract China’s investment and involvement in major construction and infrastructure projects to boost industrial and economic development. While China’s investments in Morocco and Tunisia remain at a low level, trade relations with both countries have grown steadily. Politically, China’s policy of noninterference in domestic affairs appeals to Maghreb states, which resent Western interference.
  • China’s influence in the Maghreb remains minimal. Its soft power push has struggled to promote advantages of strong relations with China beyond economics. Furthermore, Morocco and Tunisia’s populations have generally scant knowledge about China’s politics and culture. China has tried to address this lack of familiarity through the establishment of Confucius Institutes and other cultural activities. However, language and cultural barriers still impede the development of close relations, compared to those China has with other countries in Africa.

POSTPONED: The Development of Libyan Armed Groups since 2014: Community Dynamics and Economic Interests

Since the overthrow of the regime of Muammar Gaddafi in 2011, Libya’s multitude of armed groups have followed a range of paths. While many of these have gradually demobilized, others have remained active, and others have expanded their influence. In the west and south of the country,  armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks.

In the east, the Libyan Arab Armed Forces projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will need to address the fears, grievances and desires of the surrounding communities, even while the development of armed groups’ capacities dilutes their accountability to those communities.

This roundtable will discuss the findings of a forthcoming Chatham House research paper, ‘The Development of Libyan Armed Groups Since 2014: Community Dynamics and Economic Interests’, which presents insights from over 200 interviews of armed actors and members of local communities and posits how international policymakers might seek to curtail the continued expansion of the conflict economy.

Is the GCC Cyber Resilient?

9 March 2020

How would the states of the Gulf Cooperation Council (GCC) respond to a serious cyber incident? This could be a global ransomware event, a critical infrastructure incident targeted at the energy sector, or an attack on government departments. This paper examines cyber resilience in the states of the GCC.

Summary

  • GCC states seek to be leaders in digital innovation, but this leaves them vulnerable to an increasing range of cyberthreats. Governments have invested significantly in cybersecurity but these measures have been unevenly implemented, makingit difficult for these states to be resilient against a large-scale cyber incident.
  • Strategies, structures and processes (‘approaches’) for achieving cyber resilience can be conceptualized along a scale from centralized to distributed: centralized approaches maintain decision-making power in a single body, while distributed ones disperse power over many sites.
  • Centralized approaches provide more resilience against unwanted influence, while distributed approaches provide more resilience against intrusions into infrastructure. The GCC states have so far prioritized centralized over distributed cyber resilience, seeking internet and social media control over sustainable network recovery.
  • GCC governments should make a sustainable commitment to cyber resilience that provides clear guidance to organizations and makes best use of emerging cybersecurity structures. This may involve further engagement with international initiatives and partners to increase cyber resilience.
  • Given limited resources, GCC governments should rebalance their efforts from centralized towards distributed approaches to resilience.
  • GCC governments should examine the impact of relevant new technologies, discussing openly the risks of these technologies and appropriate solutions.

Summary

  • Libya’s multitude of armed groups have followed a range of paths since the emergence of a national governance split in 2014. Many have gradually demobilized, others have remained active, and others have expanded their influence. However, the evolution of the Libyan security sector in this period remains relatively understudied. Prior to 2011, Libya’s internal sovereignty – including the monopoly on force and sole agency in international relations – had been personally vested in the figure of Muammar Gaddafi. After his death, these elements of sovereignty reverted to local communities, which created armed organizations to fill that central gap. National military and intelligence institutions that were intended to protect the Libyan state have remained weak, with their coherence undermined further by the post-2014 governance crisis and ongoing conflict. As a result, the most effective armed groups have remained localized in nature; the exception is the Libyan Arab Armed Forces (LAAF), which has combined and amalgamated locally legitimate forces under a central command.
  • In the west and south of the country, the result of these trends resembles a kind of inversion of security sector reform (SSR) and disarmament, demobilization and reintegration (DDR): the armed groups have used their state affiliation to co-opt the state and professionals from the state security apparatus into their ranks; and have continued to arm, mobilize and integrate themselves into the state’s security apparatus without becoming subservient to it. In the eastern region, the LAAF projects a nationalist narrative yet is ultimately subservient to its leader, Field Marshal Khalifa Haftar. The LAAF has co-opted social organizations to dominate political and economic decision-making.
  • The LAAF has established a monopoly over the control of heavy weapons and the flow of arms in eastern Libya, and has built alliances with armed groups in the east. Armed groups in the south have been persuaded to join the LAAF’s newly established command structure. The LAAF’s offensive on the capital, which started in April 2019, represents a serious challenge to armed groups aligned with the Tripoli-based Government of National Accord (GNA). The fallout from the war will be a challenge to the GNA or any future government, as groups taking part in the war will expect to be rewarded. SSR is thus crucial in the short term: if the GNA offers financial and technical expertise and resources, plus legal cover, to armed groups under its leadership, it will increase the incentive for armed groups to be receptive to its plans for reform.
  • Prevailing policy narratives presuppose that the interests of armed actors are distinct from those of the communities they claim to represent. Given the degree to which most armed groups are embedded in local society, however, successful engagement will necessarily rely on addressing the fears, grievances and desires of the surrounding communities. Yet the development of armed groups’ capacities, along with their increasing access to autonomous means of generating revenue, has steadily diluted their accountability to local communities. This process is likely to be accelerated by the ongoing violence around Tripoli.
  • Communities’ relationship to armed groups varies across different areas of the country, reflecting the social, political, economic and security environment:
  • Despite their clear preference for a more formal, state-controlled security sector, Tripoli’s residents broadly accept the need for    the presence of armed groups to provide security. The known engagement of the capital’s four main armed groups in criminal activity is a trade-off that many residents seem able to tolerate, providing that overt violence remains low. Nonetheless, there is a widespread view that the greed of Tripoli’s armed groups has played a role in stoking the current conflict.
  • In the east, many residents appear to accept (or even welcome) the LAAF’s expansion beyond the security realm, provided that it undertakes these roles effectively. That said, such is the extent of LAAF control that opposition to the alliance comes at a high price.
  • In the south, armed groups draw heavily on social legitimacy, acting as guardians of tribal zones of influence and defenders of their respective communities against outside threats, while also at times stoking local conflicts. Social protections continue to hold sway, meaning that accountability within communities is also limited.
  • To varying extents since 2014, Libya’s armed groups have developed networks that enmesh political and business stakeholders in revenue-generation models:
  • Armed groups in Tripoli have compensated for reduced financial receipts from state budgets by cultivating unofficial and illicit sources of income. They have also focused on infiltrating state institutions to ensure access to state budgets and contracts dispersed in the capital.
  • In the east of the country, the LAAF has developed a long-term strategy to dominate the security, political and economic spheres through the establishment of a quasi-legal basis for receiving funds from Libya’s rival state authorities. It has supplemented this with extensive intervention in the private sector. External patronage supports military operations, but also helps to keep this financial system, based on unsecured debt, afloat.
  • In the south, limited access to funds from the central state has spurred armed groups to become actively involved in the economy. This has translated into the taxation of movement and the imposition of protection fees, particularly on informal (and often illicit) activity.
  • Without real commitment from international policymakers to enforcing the arms embargo and protecting the economy from being weaponized, Libya will be consigned to sustained conflict, further fragmentation and potential economic collapse. Given the likely absence of a political settlement in the short term, international policymakers should seek to curtail the continued expansion of the conflict economy by reducing armed groups’ engagement in economic life.
  • In order to reduce illicit activities, international policymakers should develop their capacity to identify and target chokepoints along illicit supply chains, with a focus on restraining activities and actors in closest proximity to violence. Targeted sanctions against rent maximizers (both armed and unarmed) is likely to be the most effective strategy. More effective investigation and restraint of conflict economy actors will require systemic efforts to improve transparency and enhance the institutional capacity of anti-corruption authorities. International policymakers should also support the development of tailored alternative livelihoods that render conflict economy activities less attractive.

The first months of 2020 have proven tumultuous for Iraq. The US killing of Iranian General Qassem Soleimani in January threatened to engulf the region in war and led to continued tit-for-tat violence between the US and Iran that has become almost a daily reality in Baghdad.

Amid the ongoing protests that since last October have challenged the social contract and led to a violent response claiming 600 deaths and injuring tens of thousands, the government is still without a prime minister after Adil abd al-Mehdi's resignation in November 2019, leaving the country directionless.

Most recently, the spread of COVID-19 threatens to expose a mismanaged healthcare system. At the same time, the rapid fall in the price of oil has impacted the government's ability to respond to or cope with these crises.

At this virtual roundtable, part of the Chatham House Iraq Initiative, experts explore these developments and try to unpack the implications for Iraq’s fragile peace and stability.

Webinar: Can the Justice and Development Party Still Absorb Popular Anger in Morocco?

Webinar Research Event

8 April 2020 - 1:00pm to 2:00pm

Event participants

Mohammed Masbah, Director, Moroccan Institute for Policy Analysis; Associate Fellow, MENA Programme, Chatham House
Moderator: Lina Khatib, Director, MENA Programme, Chatham House

Ever since independence, the Moroccan monarchy has used political parties to legitimize the country’s authoritarian political process and structure, and to absorb social and political anger. The palace puts successive governments and other elected institutions, such as local and regional councils, at the frontline of public blame, and replaces them once they fail this function.

In a recent article, MENA Programme Associate Fellow, Mohammed Masbah, examines how the Moroccan monarchy has used this strategy with the ruling Justice and Development Party (PJD) so that the palace remains the centre of political power, while the PJD – and other political parties before it– takes responsibility for coping with the mounting socio-economic crisis.

In this webinar, part of the Chatham House project on The Future of the State in the Middle East and North Africa, the article’s author will discuss the risks this approach presents for the long-term stability of Morocco and what reforms are needed to increase citizens’ dwindling confidence in the political process.

Webinar: Federalism in a Fragmented State: Rethinking Decentralization in Yemen

Research Event

15 April 2020 - 1:00pm to 2:00pm

Event participants

Osamah Al Rawhani, Deputy Director, Sana’a Center for Strategic Studies
Moderator: Nadim Houry, Executive Director, Arab Reform Initiative

Yemen suffered from the excessive control of the central government prior to the current conflict. Federalism has been put forward by many Yemeni political parties since the National Dialogue Conference (NDC) as the supposed magic cure for this significant problem. Today, Yemen is more fragmented than ever, its state central institutions have been scattered and lack leadership and the state has lost most of its sovereignty. The prevailing narrative that decentralization through federalism is Yemen’s inevitable path post-conflict often fails to acknowledge that there are prerequisites for effective local governance, beyond political will.  

In a recent article, Osamah Al Rawhani addressed how the weakness of central state institutions is the key challenge to proceeding with federalism in Yemen and highlighted prerequisites and contextual factors that need to be addressed before reforming the structure of the state. He argued that the viability of decentralization relies on the presence of a functioning, representative central government that is capable of devolving power but also able to keep the state from further fragmentation. 

In this webinar, part of the Chatham House project on The Future of the State in the Middle East and North Africa, the article’s author will discuss recent developments in Yemen, where shifting frontlines and regional divisions are fragmenting the country in new ways. The speaker will explore alternative approaches to pursue the path of federalism that recognize the current realities and the critical need for strong central institutions. He will also survey the internal and external factors that must be considered to rebuild a stable state in Yemen.

COVID 19: Assessing Vulnerabilities and Impacts on Iraq

Following 17 years of conflict and fragile state-society relations, the war-torn country is particularly vulnerable to the pandemic.

Iraq is a country already in turmoil, suffering fallout from the major military escalation between the US and Iran, mass protests calling for an end to the post-2003 political system, and a violent government crackdown killing more than 600 and wounding almost 30,000 - all presided over by a fragmented political elite unable to agree upon a new prime minister following Adil abd al-Mehdi’s resignation back in November.

COVID-19 introduces yet another threat to the fragile political order, as the virus exposes Iraq’s ineffective public health system dismantled through decades of conflict, corruption and poor governance.

Iraqi doctors are making every effort to prepare for the worst-case scenario, but they do so with huge structural challenges. The Ministry of Health lacks enough ICU beds, human resources, ventilators, and personal protective equipment (PPE). Bogged down in bureaucracy, the ministry is struggling to process procurements of equipment and medications, and some doctors have made purchases themselves.

But individual efforts can only go so far as many Iraqi doctors are concerned the official numbers of confirmed COVID-19 cases do not reflect the complexity of the situation on the ground.

The ministry relies predominately upon patients self-presenting at designated public hospitals and has only just begun community-based testing in areas of suspected clusters. Reliance on self-presentation requires a level of trust between citizens and state institutions, which is at a historic low. This gap in trust – 17 years in the making – puts Iraq’s COVID-19 response particularly at risk.

Iraq’s myriad vulnerabilities

Certain social and political factors leave Iraq uniquely exposed to the coronavirus. The country’s vulnerability is tied directly to its social, religious and economic interconnections with Iran, an epicenter of the pandemic.

Exchanges between Iran and Iraq are concentrated in two regions, with strong cross-border links between Iraqi and Iranian Kurds in the north-east, and Iraqi and Iranian Shia pilgrims in the south. Cross-border circulation of religious pilgrims is particularly concerning, as they can result in mass ritual gatherings.

The high number of confirmed cases in the southern and northern peripheries of the country puts a spotlight on Iraq's failure in managing healthcare. The post-2003 government has failed to either rebuild a robust centralized healthcare system, or to pave the way for a federalized model.

Caught in an ambiguous middle between a centralized and federalized model, coordination across provinces and hospitals during the coronavirus crisis has neither reflected strong management from Baghdad nor robust ownership at the governorate level.

This problem is part of a wider challenge of managing centre-periphery relations and federalism, which since 2003 has not worked effectively. Baghdad has provided all 18 provinces with instructions on testing and treatment, but only a handful have enough resources to put them into practice. Advanced testing capacity is limited to the five provinces with WHO-approved centers, with the remaining 13 sending swabs to Baghdad.

But the greatest challenge to Iraq’s COVID-19 response is the dramatic deterioration of state-society relations. Studies reveal a profound societal distrust of Iraq’s public healthcare institutions, due to corruption and militarization of medical institutions. Numerous videos have recently circulated of families refusing to turn over sick members - particularly women - to medical teams visiting households with confirmed or suspected cases.

As medical anthropologist Omar Dewachi notes, the ‘moral economy of quarantine’ in Iraq is heavily shaped by a history of war and its impact on the relationship between people and the state. Although local and international media often interpret this reluctance to undergo quarantine as a matter of social or tribal norms, distrusting the state leads many families to refuse quarantine because they believe it resembles a form of arrest.

The management of coronavirus relies upon an overt convergence between medical institutions and security forces as the federal police collaborate with the Ministry of Health to impose curfews and enforce quarantine. This means that, troublingly, the same security establishment which violently cracked down on protesters and civil society activists is now the teeth behind Iraq’s COVID-19 response.

Without trust between society and the political class, civil society organizations and protest movements have directed their organizational structure towards awareness-raising across Iraq. Key religious authorities such as Grand Ayatollah Sistani have called for compliance to the curfew and mobilized charitable institutions.

However, such efforts will not be enough to make up for the lack of governance at the level of the state. In the short-term, Iraq’s medical professionals and institutions are in dire need of technical and financial support. In the long-term, COVID-19 is a lesson that Iraq’s once robust public healthcare system needs serious investment and reform.

COVID-19 may prove to be another catalyst challenging the ‘muddle through’ logic of the Iraqi political elite. International actors have largely been complicit in this logic, directing aid and technical support towards security forces and political allies in the interest of short-term stability, and neglecting institutions which Iraqis rely on for health, education, and well-being.

The response to the crisis requires cooperation and buy-in of a population neglected by 17 years of failed governance. This is a seminal event that may push the country to the brink, exposing and stirring underlying tensions in state-society relations.

Webinar: Reimagining the Role of State and Non-State Actors in (Re)building National Health Systems in the Arab World

Research Event

22 April 2020 - 1:00pm to 2:00pm

Event participants

Fadi El-Jardali, Professor of Health Policy and Systems, American University of Beirut
Moderator: Nadim Houry, Executive Director, Arab Reform Initiative

As new cases of COVID-19 continue to surge, countries around the world struggle to mitigate the public health and economic effects of the virus. It is becoming increasingly clear that an effective pandemic response requires a whole-of-government, whole-of-society approach. In the Arab world, where health systems are already strained by armed conflicts and displaced populations, a whole-of-society response to the pandemic is particularly critical as countries have become increasingly dependent on non-state actors, notably the private sector, for healthcare provision and any response that includes the state alone may not be sufficient to address the pandemic.

In a recent article, Fadi El-Jardali, argued that while the pandemic will have grave health and economic consequences for years to come, it brings with it a valuable opportunity to re-envision the role of state and non-state actors in strengthening health systems. The article addressed the need for increased collaboration between state and non-state actors, and the rethinking of existing cooperation models to provide quality healthcare services for all.  

In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, Dr El-Jardali will discuss how state and non-state actors can collaborate more effectively to address the shortcomings of national health care systems amidst the pandemic and beyond. The article’s author will share insights on the different capacities available in Arab societies that governments can draw upon to ensure that Universal Health Coverage, equity considerations and social justice are at the core of health systems.

Webinar: Egypt and the Gulf: Allies and Rivals

Research Event

23 April 2020 - 1:00pm to 2:00pm

Event participants

Speaker: David Butter, Associate Fellow, Middle East and North Africa Programme, Chatham House
Moderator: Mohamed El Dahshan, Associate Fellow, Middle East and North Africa Programme, Chatham House

The webinar will be livestreamed on the MENA Programme Facebook page.

Egypt and the Gulf Arab region have long been important poles of political, military, economic and cultural power and influence in the Middle East. A recently published Chatham House paper examines the strategic and economic relationship between Egypt and the Gulf, focusing in particular on the period since Abdel-Fattah el-Sisi came to power in Egypt. Author David Butter offers a detailed evaluation of these economic relationships, in the broader context of a strategic alliance that, since 2013, has been informed by a common commitment between Egypt and the UAE in particular to keep in check the Muslim Brotherhood and its regional state supporters, primarily Turkey and Qatar.

In this webinar, the author will discuss the paper’s main argument, namely, that the degree of Egypt’s dependence on Gulf countries has fluctuated, and that by 2019, Egypt’s direct financial dependence on the Gulf was significantly reduced by comparison with the initial three years of the Sisi era, although other economic linkages such as investment, trade, remittances and tourism remained strong, with potential for growth. The speaker will also discuss the impact of the global crisis caused by the COVID-19 pandemic on Egypt’s and Gulf countries’ economies and will explore the implications for the relationship between Egypt and the Gulf.

This webinar is part of the Chatham House Middle East and North Africa Programme's Online Event Series. The event will be held on the record.

Since the start of 2020, Iran has been beset with multiple challenges including the spread of COVID-19, economic pressure from US sanctions, parliamentary elections in February, the killing of Qassem Soleimani and an increase in tensions in Iraq. The Trump administration interprets these domestic and regional challenges faces by Iran as evidence that its maximum pressure campaign is proving to be effective.

In this webinar, speakers will examine the economic and political impact of the Trump administration's policy towards Iran. Panelists will consider how these events are impacting internal dynamics in Iran and examine the economic impact of sanctions. They will also evaluate European diplomatic efforts to preserve the Iran nuclear agreement, and consider the future trajectory of US Iran policy and the potential for escalation in the region.

Webinar: Will COVID-19 Mark the Endgame for Iraq's Muhasasa Ta'ifia?

Research Event

30 April 2020 - 2:00pm to 3:00pm

Event participants

Ahmed Tabaqchali, Chief Investment Officer, Asia Frontier Capital Iraq Fund; Adjunct Assistant Professor, American University of Iraq Sulaimani
Moderator: Renad Mansour, Senior Research Fellow, Middle East and North Africa Programme, Chatham House

Control of oil rents underpins Iraq’s post-2003 political order. This political order, known as Muhasasa Ta’ifia (ethno-sectarian apportionment), features an elite bargain inclusive of all major ethnic and sect-based political groups. It has enabled the state's continuity and apparent stability through multiple crises, including the 2008 financial crisis, the 2014 oil crisis, and the war with ISIS.

In a recent article, Ahmed Tabaqchali examines how the crash in oil rents, brought about by COVID-19’s disruption of the world economy, exposes the structural inconsistencies and inherent contradictions of the Muhasasa Tai’fia system. The article argues that the current Iraqi political elite is ill-equipped to resolve the multi-faceted challenge facing the country because of its increasing fragmentation and the erosion of its legitimacy, advanced institutional decay and fundamentally different oil dynamics.

In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, the article’s author will discuss the deficiencies of the Muhasasa Ta’ifia system and will offer his insight into the future of this governance model in the context of a worsening economic crisis resulting from the COVID-19 pandemic and existing demographic pressures.

Breaking the Cycle of Violence: Transitional Justice for the Victims of ISIS in Syria

28 April 2020

This paper aims to assist the region’s local authorities, and their key foreign backers, in understanding how transitional justice can provide alternative avenues for holding local ISIS members to account while contributing to the healing of communities.

Summary

  • Following the territorial defeat of Islamic State of Iraq and Syria (ISIS) in northeastern Syria, the Kurdish-led autonomous administration in the region is now grappling with the task of quickly dealing with thousands of the group’s detained members while bringing justice to their victims. To that end, local authorities are focusing on the use of counterterrorism laws and courts to charge captured ISIS members and determine their guilt accordingly.
  • The piecemeal approach to justice is deeply flawed, and raises particular concerns about due process. No precise instruments exist to determine the personal responsibility of ISIS individuals for specific crimes, or for their role in war crimes committed by the group. In any event, the scale of the crimes and the number of victims – as well as severe shortages of resources and workers – make dispensation of justice extremely difficult through the traditional legal system.
  • Not all detained ISIS members receive prison sentences. Individuals who did not hold senior roles in the group’s apparatus and are not accused of ‘major’ crimes (in practice, largely defined as fighting for ISIS and murder) are being released under limited reconciliation deals with tribal leaders. But the involvement of local community leaders in those efforts is not enough to ensure positive results. Many victims are upset at seeing ISIS members walk free without even admitting their guilt publicly or apologizing for the pain they caused.
  • To overcome the limitations of the current, counterterrorism-focused framework, a ‘transitional justice’ approach could provide judicial and non-judicial instruments to establish accountability for ISIS crimes and reduce community resistance to the reintegration of group members. A combination of non-judicial mechanisms such as truth commissions, missing persons’ committees, and reparations and victim-healing programmes could play a vital role in providing ISIS victims with a sense of justice while contributing to peacebuilding and stability.
  • Ignoring the urgency of developing a long-term plan to serve justice and contribute to community healing will almost certainly allow ISIS to continue to prevent the recovery and development of northeastern Syria. This, in turn, risks undermining the stability of the country and the region at large.

Lebanese Women and the Politics of Disruption

Research Event

6 May 2020 - 1:00pm to 2:00pm

Event participants

Carmen Geha, Assistant Professor of Public Administration, Leadership and Organisational Development, American University of Beirut
Moderator: Lina Khatib, Director, Middle East and North Africa Programme, Chatham House
Lebanese women have been at the forefront of the protest movement that has shaken Lebanon since October 2019. The active participation by women and their visibility in Lebanon's protest movement has challenged the gender norms prevalent in Lebanese society and politics. However, the COVID-19 pandemic and the nationwide lockdown that ensued has disrupted women's ability to organize, and is threatening the fragile progress towards female inclusion in the political process.
 
In a recent article, Carmen Geha discussed the politics of representation in the context of women's participation in public life in Lebanon and argued that the country's political system is maintained through tightly-knit informal power relations among sectarian politicians, making women's participation in politics virtually impossible. The article explained how the October 2019 revolution challenged that norm by creating inclusive spaces where women activists could confront politicians and thus, transform the way women participate in politics and public life.
 
In this webinar, part of the Chatham House project on the future of the state in the Middle East and North Africa, the article's author will discuss how women's activism in Lebanon has been affected by the coronavirus-induced lockdown. The speaker will consider how, under current circumstances, women activists can speak up collectively and bring back a movement to contest gender norms in order to build an alternative political model that can better represent women's priorities.

COVID-19 Crisis – Business as Usual for Gaza?

6 May 2020

Mohammed Abdalfatah

Asfari Foundation Academy Fellow
The COVID-19 pandemic has brought unprecedented challenges, economic collapse and strict lockdowns in many parts of the world. For the people of Gaza, this reality is nothing new.

2020-05-06-covid-19-gaza.jpg

In August 2012, when the UN released its report Gaza in 2020: A liveable place?, they could not have imagined what the world would look like in 2020: cities under lockdown, restrictions on movement, border closures, widespread unemployment, economic collapse, fear and anxiety and, above all, uncertainty about what the future holds.

For Gaza’s population of 2 million people this reality is nothing new. The conditions that the rest of the world are currently experiencing as a result of the COVID-19 pandemic is similar to the tight blockade Gaza has been living under ever since Hamas took over in 2007. Israel has imposed severe restrictions on the movement of people and goods, youth unemployment has reached 60 per cent, and over 80 per cent of Gaza’s population are now dependent on international aid.

The people of Gaza are having to face the COVID-19 crisis already at a disadvantage, with poor infrastructure, limited resources and a shortage of the most basic services, such as water and power supply. It also has a fragile health system, with hospitals lacking essential medical supplies and equipment, as well as the capacity to deal with the outbreak as there are only 84 ICU beds and ventilators available.

 

Meanwhile, intra-Palestinian divisions have persisted and were evident in the initial reaction to the pandemic. When President Mahmoud Abbas announced a state of emergency, it took two days for the Hamas-led government in Gaza to follow suit and shut down schools and universities. They later made a separate emergency appeal to address the crisis and prepare for a COVID-19 response in Gaza. This lack of coordination is typical of the way the Palestinian Authority and Hamas approach crisis situations.

After the initial uncoordinated response, Hamas, as the de-facto ruler of Gaza, has asserted its ability to control Gaza’s borders by putting in place quarantine measures for everyone who enters the strip, whether through the Erez checkpoint with Israel or the Rafah border with Egypt. They have also assigned 21 hospitals, hotels, and schools as compulsory quarantine centres for all arrivals from abroad, who have to stay in quarantine for 21 days. In comparison, there are 20 quarantine centres in the West Bank.  These strict measures have prevented the spread of the virus in the community and confined it to the quarantine centres, with only 20 confirmed cases of COVID-19 as of 6 May. Gaza’s de-facto authorities have also been able to monitor markets and prices to ensure the availability of essential goods.

Faced with a major crisis, Al-Qassam Brigades – the armed wing of Hamas – have tried to play the role of a national army by participating in efforts to fight the pandemic. They have relatively good logistical capacity and have contributed to the construction of two quarantine facilities with a total capacity of 1,000 units to prepare for more arrivals into Gaza. At the local level, municipalities have been disinfecting public spaces and facilities in addition to disseminating information about the virus and related preventative and protective measures. Other precautionary measures put in place include closing the weekly open markets, and restricting social gatherings like weddings and funerals.

Despite COVID-19, it’s business as usual when it comes to international dealings with Gaza. The key parties in the conflict – Israel, Hamas and the Palestinian Authority – along with the main external actors – Egypt, the United Nations and Qatar – have continued to stick to their policies aimed at keeping the security situation under control and preventing further escalation. Although Israel has allowed entry of pharmaceutical supplies and medical equipment into Gaza during the pandemic, it has kept its restrictions on the movement of goods and people in place, while keeping a close eye on the development of the COVID-19 outbreak in Gaza – a major outbreak here would be a nightmare scenario for Israel.

Meanwhile, Qatar has continued to address the humanitarian and economic needs of Gaza in an attempt to ease the pressure and prevent further escalation. It has pledged $150 million over the next six months to help families in Gaza from poorer backgrounds. Gaza has also been discussed by the Middle East Quartet, as Nickolay Mladenov, the UN special coordinator for the Middle East Peace Process, expressed his concern about the risk of a disease outbreak in Gaza during a call with the members of the Quartet.

Amid the pandemic, threats are still being exchanged between Israel and Hamas. The Israeli defence minister, Naftali Bennett, requested that in return for providing humanitarian aid to Gaza, Hamas agrees to return the remains of two Israeli soldiers killed in the 2014 war. While openly rejecting Bennett's statement, the leader of Hamas in Gaza, Yahya Sinwar, has offered to move forward with a prisoner swap deal if Israel agrees to release elderly prisoners and detainees in addition to detained women and children. Though dealing with its own COVID-19 outbreak, Egypt has started to mediate between the two parties in an attempt to stabilize the situation and reach a prisoner swap deal.

In the wake of this pandemic, lessons should be learned and policies should be examined, by all parties. Firstly, Israel should re-evaluate its security measures towards Gaza by easing restrictions on movement and trade which would have a positive impact on living conditions for Gaza’s population. The current measures have proven to be unsustainable and have contributed to the endless cycle of violence. Secondly, the intra-Palestinian division should end, to save Palestinians from contradictory policies and insufficient capacity on both sides. In fact, all previous attempts have failed to end this self-destructive division and this is due to the absence of political will on both sides. Elections seem to be the only viable path towards unity. Finally, efforts by the international community should go beyond stabilizing the security situation and ongoing crisis inside Gaza, where disruption of normal life is the norm.

While the world has reacted to this pandemic with a whole host of new policies and emergency measures, it has remained business as usual when dealing with Gaza. Should COVID-19 spread in Gaza, its people – who have already paid the price of a continuous blockade and intra-Palestinian division for 13 years – will pay a heavy price yet again. However, this time it is not a crisis that they alone will have to face.

Extracytoplasmic sugar decoration of glycopolymer components of the bacterial cell wall contributes to their structural diversity. Typically, the molecular mechanism that underpins such a decoration process involves a three-component glycosylation system (TGS) represented by an undecaprenyl-phosphate (Und-P) sugar-activating glycosyltransferase (Und-P GT), a flippase, and a polytopic glycosyltransferase (PolM GT) dedicated to attaching sugar residues to a specific glycopolymer. Here, using bioinformatic analyses, CRISPR-assisted recombineering, structural analysis of cell wall–associated polysaccharides (CWPS) through MALDI-TOF MS and methylation analysis, we report on three such systems in the bacterium Lactococcus lactis. On the basis of sequence similarities, we first identified three gene pairs, csdAB, csdCD, and csdEF, each encoding an Und-P GT and a PolM GT, as potential TGS component candidates. Our experimental results show that csdAB and csdCD are involved in Glc side-chain addition on the CWPS components rhamnan and polysaccharide pellicle (PSP), respectively, whereas csdEF plays a role in galactosylation of lipoteichoic acid (LTA). We also identified a potential flippase encoded in the L. lactis genome (llnz_02975, cflA) and confirmed that it participates in the glycosylation of the three cell wall glycopolymers rhamnan, PSP, and LTA, thus indicating that its function is shared by the three TGSs. Finally, we observed that glucosylation of both rhamnan and PSP can increase resistance to bacteriophage predation and that LTA galactosylation alters L. lactis resistance to bacteriocin.

Biosynthesis of depsipeptides with a 3-hydroxybenzoate moiety and selective anticancer activities involves a chorismatase [Metabolism]

Neoantimycins are anticancer compounds of 15-membered ring antimycin-type depsipeptides. They are biosynthesized by a hybrid multimodular protein complex of nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS), typically from the starting precursor 3-formamidosalicylate. Examining fermentation extracts of Streptomyces conglobatus, here we discovered four new neoantimycin analogs, unantimycins B–E, in which 3-formamidosalicylates are replaced by an unusual 3-hydroxybenzoate (3-HBA) moiety. Unantimycins B–E exhibited levels of anticancer activities similar to those of the chemotherapeutic drug cisplatin in human lung cancer, colorectal cancer, and melanoma cells. Notably, they mostly displayed no significant toxicity toward noncancerous cells, unlike the serious toxicities generally reported for antimycin-type natural products. Using site-directed mutagenesis and heterologous expression, we found that unantimycin productions are correlated with the activity of a chorismatase homolog, the nat-hyg5 gene, from a type I PKS gene cluster. Biochemical analysis confirmed that the catalytic activity of Nat-hyg5 generates 3-HBA from chorismate. Finally, we achieved selective production of unantimycins B and C by engineering a chassis host. On the basis of these findings, we propose that unantimycin biosynthesis is directed by the neoantimycin-producing NRPS–PKS complex and initiated with the starter unit of 3-HBA. The elucidation of the biosynthetic unantimycin pathway reported here paves the way to improve the yield of these compounds for evaluation in oncotherapeutic applications.

The transcriptional regulator IscR integrates host-derived nitrosative stress and iron starvation in activation of the vvhBA operon in Vibrio vulnificus [Gene Regulation]

For successful infection of their hosts, pathogenic bacteria recognize host-derived signals that induce the expression of virulence factors in a spatiotemporal manner. The fulminating food-borne pathogen Vibrio vulnificus produces a cytolysin/hemolysin protein encoded by the vvhBA operon, which is a virulence factor preferentially expressed upon exposure to murine blood and macrophages. The Fe-S cluster containing transcriptional regulator IscR activates the vvhBA operon in response to nitrosative stress and iron starvation, during which the cellular IscR protein level increases. Here, electrophoretic mobility shift and DNase I protection assays revealed that IscR directly binds downstream of the vvhBA promoter PvvhBA, which is unusual for a positive regulator. We found that in addition to IscR, the transcriptional regulator HlyU activates vvhBA transcription by directly binding upstream of PvvhBA, whereas the histone-like nucleoid-structuring protein (H-NS) represses vvhBA by extensively binding to both downstream and upstream regions of its promoter. Of note, the binding sites of IscR and HlyU overlapped with those of H-NS. We further substantiated that IscR and HlyU outcompete H-NS for binding to the PvvhBA regulatory region, resulting in the release of H-NS repression and vvhBA induction. We conclude that concurrent antirepression by IscR and HlyU at regions both downstream and upstream of PvvhBA provides V. vulnificus with the means of integrating host-derived signal(s) such as nitrosative stress and iron starvation for precise regulation of vvhBA transcription, thereby enabling successful host infection.

Substrate recognition and ATPase activity of the E. coli cysteine/cystine ABC transporter YecSC-FliY [Microbiology]

Sulfur is essential for biological processes such as amino acid biogenesis, iron–sulfur cluster formation, and redox homeostasis. To acquire sulfur-containing compounds from the environment, bacteria have evolved high-affinity uptake systems, predominant among which is the ABC transporter family. Theses membrane-embedded enzymes use the energy of ATP hydrolysis for transmembrane transport of a wide range of biomolecules against concentration gradients. Three distinct bacterial ABC import systems of sulfur-containing compounds have been identified, but the molecular details of their transport mechanism remain poorly characterized. Here we provide results from a biochemical analysis of the purified Escherichia coli YecSC-FliY cysteine/cystine import system. We found that the substrate-binding protein FliY binds l-cystine, l-cysteine, and d-cysteine with micromolar affinities. However, binding of the l- and d-enantiomers induced different conformational changes of FliY, where the l- enantiomer–substrate-binding protein complex interacted more efficiently with the YecSC transporter. YecSC had low basal ATPase activity that was moderately stimulated by apo FliY, more strongly by d-cysteine–bound FliY, and maximally by l-cysteine– or l-cystine–bound FliY. However, at high FliY concentrations, YecSC reached maximal ATPase rates independent of the presence or nature of the substrate. These results suggest that FliY exists in a conformational equilibrium between an open, unliganded form that does not bind to the YecSC transporter and closed, unliganded and closed, liganded forms that bind this transporter with variable affinities but equally stimulate its ATPase activity. These findings differ from previous observations for similar ABC transporters, highlighting the extent of mechanistic diversity in this large protein family.

NAD+ biosynthesis in bacteria is controlled by global carbon/nitrogen levels via PII signaling [Microbiology]

NAD+ is a central metabolite participating in core metabolic redox reactions. The prokaryotic NAD synthetase enzyme NadE catalyzes the last step of NAD+ biosynthesis, converting nicotinic acid adenine dinucleotide (NaAD) to NAD+. Some members of the NadE family use l-glutamine as a nitrogen donor and are named NadEGln. Previous gene neighborhood analysis has indicated that the bacterial nadE gene is frequently clustered with the gene encoding the regulatory signal transduction protein PII, suggesting a functional relationship between these proteins in response to the nutritional status and the carbon/nitrogen ratio of the bacterial cell. Here, using affinity chromatography, bioinformatics analyses, NAD synthetase activity, and biolayer interferometry assays, we show that PII and NadEGln physically interact in vitro, that this complex relieves NadEGln negative feedback inhibition by NAD+. This mechanism is conserved in distantly related bacteria. Of note, the PII protein allosteric effector and cellular nitrogen level indicator 2-oxoglutarate (2-OG) inhibited the formation of the PII-NadEGln complex within a physiological range. These results indicate an interplay between the levels of ATP, ADP, 2-OG, PII-sensed glutamine, and NAD+, representing a metabolic hub that may balance the levels of core nitrogen and carbon metabolites. Our findings support the notion that PII proteins act as a dissociable regulatory subunit of NadEGln, thereby enabling the control of NAD+ biosynthesis according to the nutritional status of the bacterial cell.

The hibernating 100S complex is a target of ribosome-recycling factor and elongation factor G in Staphylococcus aureus [Protein Synthesis and Degradation]

The formation of translationally inactive 70S dimers (called 100S ribosomes) by hibernation-promoting factor is a widespread survival strategy among bacteria. Ribosome dimerization is thought to be reversible, with the dissociation of the 100S complexes enabling ribosome recycling for participation in new rounds of translation. The precise pathway of 100S ribosome recycling has been unclear. We previously found that the heat-shock GTPase HflX in the human pathogen Staphylococcus aureus is a minor disassembly factor. Cells lacking hflX do not accumulate 100S ribosomes unless they are subjected to heat exposure, suggesting the existence of an alternative pathway during nonstressed conditions. Here, we provide biochemical and genetic evidence that two essential translation factors, ribosome-recycling factor (RRF) and GTPase elongation factor G (EF-G), synergistically split 100S ribosomes in a GTP-dependent but tRNA translocation-independent manner. We found that although HflX and the RRF/EF-G pair are functionally interchangeable, HflX is expressed at low levels and is dispensable under normal growth conditions. The bacterial RRF/EF-G pair was previously known to target only the post-termination 70S complexes; our results reveal a new role in the reversal of ribosome hibernation that is intimately linked to bacterial pathogenesis, persister formation, stress responses, and ribosome integrity.

Modification of a PE/PPE substrate pair reroutes an Esx substrate pair from the mycobacterial ESX-1 type VII secretion system to the ESX-5 system [Molecular Bases of Disease]

Bacterial type VII secretion systems secrete a wide range of extracellular proteins that play important roles in bacterial viability and in interactions of pathogenic mycobacteria with their hosts. Mycobacterial type VII secretion systems consist of five subtypes, ESX-1–5, and have four substrate classes, namely, Esx, PE, PPE, and Esp proteins. At least some of these substrates are secreted as heterodimers. Each ESX system mediates the secretion of a specific set of Esx, PE, and PPE proteins, raising the question of how these substrates are recognized in a system-specific fashion. For the PE/PPE heterodimers, it has been shown that they interact with their cognate EspG chaperone and that this chaperone determines the designated secretion pathway. However, both structural and pulldown analyses have suggested that EspG cannot interact with the Esx proteins. Therefore, the determining factor for system specificity of the Esx proteins remains unknown. Here, we investigated the secretion specificity of the ESX-1 substrate pair EsxB_1/EsxA_1 in Mycobacterium marinum. Although this substrate pair was hardly secreted when homologously expressed, it was secreted when co-expressed together with the PE35/PPE68_1 pair, indicating that this pair could stimulate secretion of the EsxB_1/EsxA_1 pair. Surprisingly, co-expression of EsxB_1/EsxA_1 with a modified PE35/PPE68_1 version that carried the EspG5 chaperone-binding domain, previously shown to redirect this substrate pair to the ESX-5 system, also resulted in redirection and co-secretion of the Esx pair via ESX-5. Our results suggest a secretion model in which PE35/PPE68_1 determines the system-specific secretion of EsxB_1/EsxA_1.

5-Ethynyl-2'-deoxycytidine and 5-ethynyl-2'-deoxyuridine are differentially incorporated in cells infected with HSV-1, HCMV, and KSHV viruses [Microbiology]

Nucleoside analogues are a valuable experimental tool. Incorporation of these molecules into newly synthesized DNA (i.e. pulse-labeling) is used to monitor cell proliferation or to isolate nascent DNA. Some of the most common nucleoside analogues used for pulse-labeling of DNA in cells are the deoxypyrimidine analogues 5-ethynyl-2'-deoxyuridine (EdU) and 5-ethynyl-2'-deoxycytidine (EdC). Click chemistry enables conjugation of an azide molecule tagged with a fluorescent dye or biotin to the alkyne of the analog, which can then be used to detect incorporation of EdU and EdC into DNA. The use of EdC is often recommended because of the potential cytotoxicity associated with EdU during longer incubations. Here, by comparing the relative incorporation efficiencies of EdU and EdC during short 30-min pulses, we demonstrate significantly lower incorporation of EdC than of EdU in noninfected human fibroblast cells or in cells infected with either human cytomegalovirus or Kaposi's sarcoma-associated herpesvirus. Interestingly, cells infected with herpes simplex virus type-1 (HSV-1) incorporated EdC and EdU at similar levels during short pulses. Of note, exogenous expression of HSV-1 thymidine kinase increased the incorporation efficiency of EdC. These results highlight the limitations when using substituted pyrimidine analogues in pulse-labeling and suggest that EdU is the preferable nucleoside analogue for short pulse-labeling experiments, resulting in increased recovery and sensitivity for downstream applications. This is an important discovery that may help to better characterize the biochemical properties of different nucleoside analogues with a given kinase, ultimately leading to significant differences in labeling efficiency of nascent DNA.

The streptococcal multidomain fibrillar adhesin CshA has an elongated polymeric architecture [Microbiology]

The cell surfaces of many bacteria carry filamentous polypeptides termed adhesins that enable binding to both biotic and abiotic surfaces. Surface adherence is facilitated by the exquisite selectivity of the adhesins for their cognate ligands or receptors and is a key step in niche or host colonization and pathogenicity. Streptococcus gordonii is a primary colonizer of the human oral cavity and an opportunistic pathogen, as well as a leading cause of infective endocarditis in humans. The fibrillar adhesin CshA is an important determinant of S. gordonii adherence, forming peritrichous fibrils on its surface that bind host cells and other microorganisms. CshA possesses a distinctive multidomain architecture comprising an N-terminal target-binding region fused to 17 repeat domains (RDs) that are each ∼100 amino acids long. Here, using structural and biophysical methods, we demonstrate that the intact CshA repeat region (CshA_RD1–17, domains 1–17) forms an extended polymeric monomer in solution. We recombinantly produced a subset of CshA RDs and found that they differ in stability and unfolding behavior. The NMR structure of CshA_RD13 revealed a hitherto unreported all β-fold, flanked by disordered interdomain linkers. These findings, in tandem with complementary hydrodynamic studies of CshA_RD1–17, indicate that this polypeptide possesses a highly unusual dynamic transitory structure characterized by alternating regions of order and disorder. This architecture provides flexibility for the adhesive tip of the CshA fibril to maintain bacterial attachment that withstands shear forces within the human host. It may also help mitigate deleterious folding events between neighboring RDs that share significant structural identity without compromising mechanical stability.

The major subunit of widespread competence pili exhibits a novel and conserved type IV pilin fold [Protein Structure and Folding]

Type IV filaments (T4F), which are helical assemblies of type IV pilins, constitute a superfamily of filamentous nanomachines virtually ubiquitous in prokaryotes that mediate a wide variety of functions. The competence (Com) pilus is a widespread T4F, mediating DNA uptake (the first step in natural transformation) in bacteria with one membrane (monoderms), an important mechanism of horizontal gene transfer. Here, we report the results of genomic, phylogenetic, and structural analyses of ComGC, the major pilin subunit of Com pili. By performing a global comparative analysis, we show that Com pili genes are virtually ubiquitous in Bacilli, a major monoderm class of Firmicutes. This also revealed that ComGC displays extensive sequence conservation, defining a monophyletic group among type IV pilins. We further report ComGC solution structures from two naturally competent human pathogens, Streptococcus sanguinis (ComGCSS) and Streptococcus pneumoniae (ComGCSP), revealing that this pilin displays extensive structural conservation. Strikingly, ComGCSS and ComGCSP exhibit a novel type IV pilin fold that is purely helical. Results from homology modeling analyses suggest that the unusual structure of ComGC is compatible with helical filament assembly. Because ComGC displays such a widespread distribution, these results have implications for hundreds of monoderm species.
