What impact is COVID-19 having on war-torn areas like Yemen, Syria, Libya

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.

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.

More flare-ups in Yemen, a country reeling under five-year-old conflict, 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.

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.

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.
