The Syrian Observatory said those involved and killed by the strikes were tribesmen loyal to President Bashar al-Assad and Shia militias of Afghanistan.
In a letter addressed to the United Nations secretary-general, the Syrian Foreign Ministry described the strike a "war crime" and called for the coalition to be dismantled, Syrian state news agency Sana said.

Syria's regime and pro-Assad Russia were furious with the strikes.

Pro-government forces had used Russian-designed T-55 and T-72 tanks to shoot at the SDF, Lt. Col. Earl Brown, a spokesman for U.S. Central Command, told VOA. Roughly a battalion of pro-regime forces launched what appeared to be a coordinated attacks supported by D-30 howitzers, Soviet-era T-54 and T-72 tanks, rockets and mortars, he said.
