A brutal war that triggered years of economic crisis and damaged vital infrastructure has put 2.9 million at risk of sliding into hunger, while another 12 million do not know where their next meal is coming from, the UN agency said.

“Hunger soars to 12-year high in Syria,” as 70 percent of the population might soon be “unable to put food on the table for their families,” the statement said.

“Syria now has the sixth highest number of food insecure people in the world,” the WFP added, with food prices increasing nearly 12-fold in three years.

Child and maternal malnutrition are also “increasing at a speed never seen before,” in more than a decade of war.

If the international community does not step up to help Syrians, it risks facing “another wave of mass migration,” said WFP Executive Director David Beasley during a visit to Syria this week.

“Is that what the international community wants?” he asked, urging donor countries to redouble efforts to “avert this looming catastrophe.”

The UN estimates 90 percent of the 18 million people in Syria are living in poverty, with the economy hit by conflict, drought, cholera and the Covid pandemic as well as the fallout from the financial crash in neighbouring Lebanon.

The conflict in Syria started with the brutal repression of peaceful protests.

About half a million people have been killed, and the conflict has forced around half of the country’s pre-war population from their homes.

Syria’s Foreign Ministry said on Saturday that a report by the Organization for the Prohibition of Chemical Weapons that found the regime was responsible for a chemical weapon attack on the city of Douma in 2018 lacked any evidence, and denied the allegations.

The global chemical weapons watchdog said on Friday a nearly two-year investigation had found that at least one Syrian military helicopter had dropped gas cylinders onto residential buildings in Douma, killing 43 people.

Investigators said there were “reasonable grounds to believe” that at least one Syrian air force helicopter had dropped two cylinders of the toxic gas on the rebel-held town of Douma during Syria’s civil war.

“The world now knows the facts,” said Fernando Arias, chief of the Organization for the Prohibition of Chemical Weapons or OPCW.

“It is up to the international community to take action,” Arias said in a statement.

Damascus and its ally Moscow claimed the April 7, 2018 attack was staged by rescue workers at the behest of the US which afterwards launched airstrikes on Syria along with Britain and France.

The Douma case also caused controversy after leaks from two former employees accused the Hague-based watchdog of altering its original findings to make them sound more convincing.

But the OPCW said its investigators had “considered a range of possible scenarios” and concluded that “the Syrian Arab Air Forces are the perpetrators of this attack.”

Western powers together called on Syria to be held accountable over the “horrific” attack.

“We call on the Russian Federation to stop shielding Syria from accountability for its use of chemical weapons,” said a joint statement by US Secretary of

State Antony Blinken and his counterparts from Britain, France and Germany.

“No amount of disinformation from the Kremlin can hide its hand in abetting the Assad regime.”
