BEIRUT — Syria’s state media say the US-led coalition has bombed government-backed troops in eastern Syria, citing reports of dozens killed and wounded.

The official state news agency SANA reported Thursday that the overnight attack hit tribal fighters in Khusham, a town in the oil-rich Deir el-Zour province.

SANA says the local fighters were battling IS militants and the US-backed Kurdish-led Syrian Democratic Forces in the area. The US military said late Wednesday it launched airstrikes on Syrian government-backed troops after as many as 500 attackers began what appeared to be a coordinated assault on the SDF accompanied by US advisers in Deir el-Zour province.

SANA called it an “aggression.” The state Al-Ikhbariyah TV said there were reports that dozens were killed.
