U.S. says Syria's Assad may again be using chemical weapons, lays blame on Russia

PARIS (Reuters) - The Syrian government may still be using chemical weapons after a suspected chlorine attack in the rebel enclave of eastern Ghouta, the United States said on Tuesday, adding that Russia ultimately bore responsibility. "Only yesterday more than 20 civilians, mostly children, were victims of an apparent chlorine gas attack," Secretary of State Rex Tillerson said after a conference on chemical weapons in Paris. "The recent attacks in East Ghouta raise serious concerns that Bashar al-Assad may be continuing to use chemical weapons against hiss own people." Tillerson added that whoever conducted the attacks, "Russia ultimately bears responsibility for the victims in eastern Ghouta and countless other Syrians targeted with chemical weapons since Russia became involved in Syria".
