Syrian government forces and U.S-backed, Kurdish-led rebels signed a ceasefire Tuesday after clashes in Aleppo left at least one person dead and several others injured.

Clashes between government troops and the Syrian Democratic Forces erupted Tuesday when SDF militias attacked troops at two checkpoints in Aleppo, the state-run Syrian Arab News Agency reported. The attacks injured at least three Syrian security troops and several civilians.

Syrian forces retaliated by firing on buildings reportedly containing SDF forces. It is unclear if the SDF forces suffered any casualties.

SDF spokesperson Farhad Shami denied accusations that its fighters carried out attacks on the Aleppo checkpoints, asserting that the rebel group has had no forces in the area since April. Mr. Shami blamed Tuesday’s violence on provocations from the Syrian government and urged Damascus to end its “stifling siege” of Aleppo.

“What is happening in the Ashrafieh and Sheikh Maqsoud neighborhoods is the result of a series of repeated attacks by Damascus government factions against the civilian population. They have imposed a stifling security and humanitarian siege, cut off aid and medical supplies, kidnapped many residents, and continued their daily provocations against residents at checkpoints,” Mr. Shami posted Tuesday on X.

Tuesday’s fighting muddies the deal from earlier this year aimed at integrating the SDF into the Syrian security forces. The U.S.-brokered deal, signed in March, would see SDF forces combine with the Syrian army and SDF leaders turn over key resources to Damascus by December.

However, Syrian troops and SDF forces have traded blows since August, with each side blaming the other for the violence. The clashes have mostly occurred in northwestern Syria, where the SDF has its largest base of Kurdish support.

Turkey, which considers the SDF to be part of a Kurdish terrorist organization, has demanded that the group follow the terms of the March agreement or face military action. The U.S., which recently lifted sanctions on Syria following the fall of then-President Bashar Assad, has also urged the SDF to make peace with Damascus.

The U.S. was one of the SDF’s principal supporters during Syria’s civil war, with Washington providing the group significant financial and military support to combat Assad-aligned troops and members of the Islamic State.
