BEIRUT (AFP) - Tens of thousands of civilians are fleeing bombardment in Syria's Idlib region, the UN said, as fighting flares in the militant bastion fuelling an already dire humanitarian situation.
The Idlib region, which is home to some three million people including many displaced by Syria's civil war, is controlled by the country's former Al-Qaeda affiliate, Hayat Tahrir al-Sham.
The Damascus regime has repeatedly vowed to take back control of it.
There has been an uptick in violence in Idlib since Monday and, despite UN calls for a de-escalation, major clashes between Syrian regime forces and armed groups has flared in the past 24 hours, killing more than 80 people on both sides, a war monitor said on Friday (Dec 20).
The fighting raged around the militant-held town of Maaret al-Numan in southern Idlib, said the Britain-based Syrian Observatory for Human Rights.
It came as warplanes from Syrian regime ally Russia pounded areas around Maaret al-Numan and the nearby town of Saraqeb with a series of air strikes, it added.
The UN humanitarian agency OCHA said tens of thousands of civilians have fled southern Idlib since Monday and headed north for safety, while thousands more were waiting for the violence to abate to leave.
"Following the intensification of air strikes and shelling since Dec 16 in southern Idlib, tens of thousands of civilians are reportedly fleeing from Maaret al-Numan area in southern Idlib governorate to (the) north," OCHA said.
The UN agency said a shortage of fuel for private vehicles is limiting the movement of civilians while roads leading out of the town are "extremely dangerous" as they are reportedly being hit by air strikes.
"Since the evening of Dec 19, residents of Maaret al-Numan town... began to communicate to the humanitarian community that they wanted to move to safety, but were unable to move due to the heavy aerial bombardment," the UN agency said.
"The numbers of families who already fled in the past 72 hours are estimated to have reached tens of thousands and there are thousands of others who are potentially waiting for the air strikes and bombardment to ease to allow them safety to move," it added.
'SITUATION IS VERY BAD'
On Friday alone, "hundreds of families are reported to have fled north", it said.
The UN agency said the displacement of civilians was straining an already dire humanitarian situation, specially because it is happening during the winter.
"Displacement happening in winter months is exacerbating the vulnerability of people in need.
"Many of those who fled are in urgent need of humanitarian support, particularly shelter, food... (and) non-food items such as winter clothes and health services," it said.
OCHA said that some of the displaced who moved north had not eaten in days.
"Renewal of intensive fighting in the south-eastern sector of the Idlib province may result in more and more people being displaced towards northern parts of Idlib," OCHA warned.
Yasser Ibrahim al-Dandal said he was fleeing with his family to olive groves in northern Idlib, where they would sleep out in the open.
"Hundreds of rockets hit Maarat al-Numan," he told AFP. "The situation is very bad."
Meanwhile, hundreds of people held a protest camp for the displaced near the border with Turkey on Friday, decrying the escalation around Maaret al-Numan.
According to the Observatory, fighting over the past 24 hours killed 42 militants, nine rebels and 30 Syrian regime loyalists.
Pro-government forces launched a blistering offensive against the region in April, killing around 1,000 civilians and displacing more than 400,000 people from their homes.
Since August, the area has supposedly been protected by a ceasefire announced by Moscow, but bombardments have persisted.
Syria's war has killed over 370,000 people and displaced millions from their homes since beginning in 2011 with the brutal repression of anti-government protests.
