TOPSHOT-SYRIA-CONFLICT-DOUMA

TOPSHOT - A Syrian girl holds an oxygen mask over the face of an infant at a make-shift hospital following a reported gas attack on the rebel-held besieged town of Douma in the eastern Ghouta region on the outskirts of the capital Damascus on January 22, 2018. At least 21 cases of suffocation, including children, were reported in Syria in a town in eastern Ghouta, a beleaguered rebel enclave east of Damascus, an NGO accusing the regime of carrying out a new chemical attack said. Since the beginning of the war in Syria in 2011, the government of Bashar al-Assad has been repeatedly accused by UN investigators of using chlorine gas or sarin gas in sometimes lethal chemical attacks.
