DAMASCUS: Syria’s military said it would open a corridor Thursday for civilians to evacuate an area of Aleppo province that has seen a military buildup following intense clashes between government and Kurdish-led forces in Aleppo city.

The army’s announcement late Wednesday — which said civilians would be able to evacuate through the “humanitarian corridor” from 9 a.m. to 5 p.m. Thursday — appeared to signal plans for an offensive in the towns of Deir Hafer and Maskana and surrounding areas, about 60 kilometers (40 miles) east of Aleppo city.

The military called on the Kurdish-led Syrian Democratic Forces and other armed groups to withdraw to the other side of the the Euphrates River, to the east of the contested zone.

Syrian government troops have already sent troop reinforcements to the area after accusing the SDF of building up its own forces there, which the SDF denied. There have been limited exchanges of fire between the two sides, and the SDF has said that Turkish drones carried out strikes there.

The government has accused the SDF of launching drone strikes in Aleppo city, including one that hit the Aleppo governorate building on Saturday shortly after two Cabinet ministers and a local official held a news conference there.
