It's a three-decade first: Presidents of US, Iran talk directly, if only by phone

Beirut, Apr 5: The novel coronavirus has put global trade on hold, placed half of the world population in confinement and has the potential to topple governments and reshape diplomatic relations.

The United Nations has appealed for ceasefires in all the major conflicts rocking the planet, with its chief Antonio Guterres on Friday warning "the worst is yet to come". But it remains unclear what the pandemic's impact will be on the multiple wars roiling the Middle East.

Here is an overview of the impact so far on the conflicts in Syria, Yemen, Libya and Iraq:

The COVID-19 outbreak turned into a pandemic just as a ceasefire reached by the two main foreign power brokers in Syria's nine-year-old war -- Russia and Turkey -- was taking effect.

The three million people living in the ceasefire zone, in the country's northwestern region of Idlib, had little hope the deal would hold.

Yet fears the coronavirus could spread like wildfire across the devastated country appear to have given the truce an extended lease of life.

According to the Syrian Observatory for Human Rights, the month of March saw the lowest civilian death toll since the conflict started in 2011, with 103 deaths.

The ability of the multiple administrations in Syria -- the Damascus government, the autonomous Kurdish administration in the northeast and the jihadist-led alliance that runs Idlib -- to manage the coronavirus threat is key to their credibility.

"This epidemic is a way for Damascus to show that the Syrian state is efficient and all territories should be returned under its governance," analyst Fabrice Balanche said.

However the pandemic and the global mobilisation it requires could precipitate the departure of US-led troops from Syria and neighbouring Iraq.

This in turn could create a vacuum in which the Islamic State jihadist group, still reeling from the demise of its "caliphate" a year ago, could seek to step up its attacks.

The Yemeni government and the Huthi rebels initially responded positively to the UN appeal for a ceasefire, as did neighbouring Saudi Arabia, which leads a military coalition in support of the government.

That rare glimmer of hope in the five-year-old conflict was short-lived however and last week Saudi air defences intercepted ballistic missiles over Riyadh and a border city fired by the Iran-backed rebels.

The Saudi-led coalition retaliated by striking Huthi targets in the rebel-held capital Sanaa on Monday.

Talks have repeatedly faltered but the UN envoy Martin Griffiths is holding daily consultations in a bid to clinch a nationwide ceasefire.

More flare-ups in Yemen could compound a humanitarian crisis often described as the worst in the world and invite a coronavirus outbreak of catastrophic proportions.

In a country where the health infrastructure has collapsed, where water is a rare commodity and where 24 million people require humanitarian assistance, the population fears being wiped out if a ceasefire doesn't allow for adequate aid.

"People will end up dying on the streets, bodies will be rotting in the open," said Mohammed Omar, a taxi driver in the Red Sea port city of Hodeida.

Much like Yemen, the main protagonists in the Libyan conflict initially welcomed the UN ceasefire call but swiftly resumed hostilities.

Fierce fighting has rocked the south of the capital Tripoli in recent days, suggesting the risk of a major coronavirus outbreak is not enough to make guns fall silent.

Turkey has recently played a key role in the conflict, throwing its weight behind the UN-recognised Government of National Accord.

Fabrice Balanche predicted that accelerated Western disengagement from Middle East conflicts could limit Turkish support to the GNA.

That could eventually favour forces loyal to eastern-based strongman Khalifa Haftar, who launched an assault on Tripoli one year ago and has the backing of Russia, Egypt and the United Arab Emirates.

Western countries have been hit hardest by the pandemic, which could prompt them to divert both military resources and peace-brokering capacity from foreign conflicts.

A report by the International Crisis Group said European officials had reported that efforts to secure a ceasefire in Libya were no longer receiving high-level attention due to the pandemic.

Iraq is no longer gripped by fully-fledged conflict but it remains vulnerable to an IS resurgence in some regions and its two main foreign backers are at each other's throats.

Iran and the United States are two of the countries most affected by the coronavirus but there has been no sign of any let-up in their battle for influence that has largely played out on Iraqi soil.

With most non-US troops in the coalition now gone and some bases evacuated, American personnel are now regrouped in a handful of locations in Iraq.

Washington has deployed Patriot air defence missiles, prompting fears of a fresh escalation with Tehran, whose proxies it blames for a spate of rocket attacks on bases housing US troops.

Riyadh, Feb 27: Saudi Arabia on Thursday halted travel to the holiest sites in Islam over fears about a new viral epidemic just months ahead of the annual hajj pilgrimage, a move coming as the Mideast has over 220 confirmed cases of the illness.

The extraordinary decision by Saudi Arabia stops foreigners from reaching the holy city of Mecca and the Kaaba, the cube-shaped structure the world's 1.8 billion Muslims pray toward five times a day. It also said travel was suspended to Prophet Muhammad's mosque in Medina.

The decision showed the worry about the outbreak potentially spreading into Saudi Arabia, whose oil-rich monarchy stakes its legitimacy on protecting Islam's holy sites. The epicenter in the Mideast's most-affected country, Iran, appears to be in the holy Shiite city of Qom, where a shrine there sees the faithful reach out to kiss and touch it in reverence.

"Saudi Arabia renews its support for all international measures to limit the spread of this virus, and urges its citizens to exercise caution before traveling to countries experiencing coronavirus outbreaks," the Saudi Foreign Ministry said in a statement announcing the decision.

"We ask God Almighty to spare all humanity from all harm." Disease outbreaks always have been a concern surrounding the hajj, required of all able-bodied Muslims once in their life, especially as pilgrims come from all over the world.

The earliest recorded outbreak came in 632 as pilgrims fought off malaria. A cholera outbreak in 1821, for instance, killed an estimated 20,000 pilgrims. Another cholera outbreak in 1865 killed 15,000 pilgrims and then spread worldwide.

More recently, Saudi Arabia faced a danger from a related coronavirus that caused Middle East respiratory syndrome, or MERS. The kingdom increased its public health measures in 2012 and 2013, though no outbreak occurred.

While millions attend the 10-day hajj, this year set for late July into early August, millions more come during the rest of the year to the holy sites in the kingdom.

"It is unprecedented, at least in recent times, but given the worldwide spread of the virus and the global nature of the umrah, it makes sense from a public health and safety point of view," said Kristian Ulrichsen, a research fellow at the James A Baker III Institute for Public Policy at Rice University. "Especially since the Iranian example illustrates how a religious crossroads can so quickly amplify the spread and reach of the virus." The virus that causes the illness named COVID-19 has infected more than 80,000 people globally, mainly in China. The hardest-hit nation in the Mideast is Iran, where Health Ministry spokesman Kianoush Jahanpour said 19 people have died among 139 confirmed cases.

Experts are concerned Iran may be underreporting cases and deaths, given the illness's rapid spread from Iran across the Persian Gulf. For example, Iran still has not confirmed any cases in Mashhad, even though a number of cases reported in Kuwait are linked to the Iranian city.

In Bahrain, which confirmed 33 cases as of Thursday morning, authorities halted all flights to Iraq and Lebanon. It separately extended a 48-hour ban overflights from Dubai and Sharjah in the United Arab Emirates, through which infected travellers reached the island kingdom off the coast of Saudi Arabia.

Iranian President Hassan Rouhani said there were no immediate plans to quarantine cities but acknowledged it may take "one, two or three weeks” to get control of the virus in Iran.

As Iran's 80 million people find themselves increasingly isolated in the region by the outbreak, the country's sanctions-battered economy saw its currency slump to its lowest level against the US dollar in a year on Wednesday.
