More than 235,000 people have fled the Idlib region over the past two weeks, the UN said Friday, amid heightened regime and Russian attacks on Syria's last major opposition bastion.
The mass displacement between 12 and 25 December has left the violence-plagued Maaret al-Numan region in southern Idlib "almost empty," the UN said in a statement.
Since mid-December, Russian-backed regime forces have pressed with an assault on militants in southern Idlib, despite an August ceasefire deal and calls for de-escalation from Turkey, France, and the United Nations.
The increased airstrikes came as Russian-backed regime forces advanced on the ground.
They have since December 19 seized dozens of towns and villages from the militants amid clashes that have killed hundreds on both sides.
The bombardment and clashes have amplified displacement from Maaret al-Numan and the nearby town Saraqeb in the southern Idlib region, the UN said.
"People from Saraqab and its eastern countryside are now fleeing in anticipation of fighting directly affecting their communities next," a statement said.
Idlib is dominated by the country's former Al-Qaeda affiliate, Hayat Tahrir al-Sham, whose chief this week urged militants and allied rebels to head to the frontlines and battle "the Russian occupiers" and the regime.
The region hosts some three million people, including many displaced by years of violence in other parts of Syria.
The Damascus regime, which now controls 70 percent of Syria, has repeatedly vowed to take back the area.
Backed by Moscow, Damascus launched a blistering offensive against Idlib in April, killing around 1,000 civilians and displacing more than 400,000 people.
Despite a ceasefire announced in August, the bombardment has continued, prompting Turkey this week to press for a fresh ceasefire deal during talks in Moscow.
France on Tuesday called for an "an immediate de-escalation," warning of deteriorating humanitarian conditions.
The war in Syria has killed more than 370,000 people and displaced millions since it began with anti-government demonstrations brutally crushed by security forces.
