Syria Condemns US Air Strike As Massacre

Overnight air strikes killed an estimated 100 pro-government fighters near the Euphrates river in Deir Ez Zour province, according to the US. The Syrian government called it a "war crime" while the US claimed a right to self-defence, saying it was responding to an attack on allied Kurdish and Arab fighters.
