In a statement on Wednesday, the US-led Coalition said it had conducted strikes against pro-regime forces after an “unprovoked” attack against the Syrian Democratic Forces. At least 100 militants affiliated with President Bashar al-Assad’s regime were reportedly killed in the Coalition’s attack.

The US-led Coalition against ISIS in Syria attacked pro-regime forces in air and artillery strikes on Wednesday, the Coalition said in a statement. The strikes came after the pro-regime militants initiated an attack against the headquarters of the Syrian Democratic Forces (SDF).

“In defense of Coalition and partner forces, the Coalition conducted strikes against attacking forces to repel the act of aggression against partners engaged in the Global Coalition’s defeat-Daesh [ISIS] mission,” read the statement. “The Coalition remains committed to focusing on the defeat-Daesh mission in the Middle Euphrates River Valley and asserts its non-negotiable right to act in self-defense.”

At least 100 militants were killed in the Coalition’s attack, a US military official told reporters on Wednesday. The official clarified that the action “was taken in self-defense” after about “20 to 30 artillery and tank rounds landed within 500 meters” of the SDF’s headquarters. No coalition or SDF member sustained any injuries, according to the official.

According to another official speaking to CNN, the US-backed Coalition was “in regular communication” with Russian military forces in the area. Nevertheless, the official said the US is looking into whether Russian-affiliated forces may have been involved. He added that the Coalition “cannot speculate on the exact makeup of the Syrian pro-regime forces who conducted the attack at this time.”
