Syrian military tells civilians to evacuate contested area east of Aleppo amid rising tensions

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.

The tensions in the Deir Hafer area come after several days of intense clashes last week in Aleppo city that ended with the evacuation of Kurdish fighters and government forces taking control of three contested neighborhoods. The fighting killed at least 23 people, wounded dozens more, and displaced tens of thousands.

The fighting broke out as negotiations have stalled between Damascus and the SDF, which controls large swaths of northeast Syria, over an agreement to integrate their forces and for the central government to take control of institutions including border crossings and oil fields in the northeast.

Some of the factions that make up the new Syrian army, which was formed after the fall of former President Bashar Assad in a rebel offensive in December 2024, were previously Turkey-backed insurgent groups that have a long history of clashing with Kurdish forces.

The SDF for years has been the main U.S. partner in Syria in fighting against the Islamic State group, but Turkey considers the SDF a terrorist organization because of its association with the Kurdistan Workers’ Party, or PKK, which has waged a long-running insurgency in Turkey. A peace process is now underway.

Despite the long-running U.S. support for the SDF, the Trump administration has also developed close ties with the government of interim Syrian President Ahmad al-Sharaa and has pushed the Kurds to implement the integration deal. Washington has so far avoided publicly taking sides in the clashes in Aleppo.

The SDF in a statement warned of “dangerous repercussions on civilians, infrastructure, and vital facilities” in case of a further escalation and said Damascus bears “full responsibility for this escalation and all ensuing humanitarian and security repercussions in the region.”

Adm. Brad Cooper, commander of U.S. Central Command, said in a statement Tuesday that the U.S. is “closely monitoring” the situation and called for “all parties to exercise maximum restraint, avoid actions that could further escalate tensions, and prioritize the protection of civilians and critical infrastructure.” He called on the parties to “return to the negotiating table in good faith.”
