BEIRUT (Reuters) – Rapid advances by the Syrian army into rebels’ largest remaining stronghold, Idlib province, have brought it closer to a key insurgent-held military airport and displaced tens of thousands of people struggling to find shelter in winter weather.
Supported by Iran-backed militias and Russian air power, President Bashar al-Assad’s forces have taken territory in northeastern Hama and southern Idlib provinces since beginning an offensive in late October.
The fighting and air strikes have forced more than 60,000 people to leave their homes since Nov. 1, according to the U.N. Office for the Coordination of Humanitarian Affairs (OCHA).
In recent days the offensive has escalated, with forces progressing towards the strategic Abu al-Duhur military airport, to which rebels laid siege in 2012 before completely ousting Assad’s forces in September 2015.
A commander in a military alliance fighting in support of Damascus has said the army and its allies intend to capture the air base.
The Syrian Observatory for Human Rights said on Friday the Syrian army and its allies had taken around 84 villages since Oct. 22, including at least 14 in the past 24 hours.
The Britain-based war monitor said the rapid advance this week was made possible by intense air strikes which caused rebels to withdraw.
The Syrian army lost Idlib province, which borders Turkey, to insurgents when the provincial capital fell to insurgents in 2015. It became the only province fully under opposition control.
Tahrir al-Sham, spearheaded by al-Qaeda’s former branch in Syria formerly called the Nusra Front, is the main rebel force in the province.
A Syrian military source said the Nusra Front and its allies are the target of the military operation in northeast Hama and southeast Idlib provinces.
“The army’s operations there are continuing and the army is achieving advances. The terrorists (are facing) big losses in the area,” he told Reuters.
Idlib is part of Russian-engineered “de-escalation zones” meant to reduce fighting in western Syria. Turkish troops are also present in northern Idlib under the de-escalation deal struck with Assad’s allies Russia and Iran.
“De-escalation zones do not cover the Nusra Front at all, and the Nusra Front is in reality the one fully controlling Idlib,” the military source said.
Tahrir al-Sham is simultaneously under attack from Islamic State, which has been expanding a small pocket of territory in northeastern Hama on the edge of…
