White Helmets members put skeletal remains and corpses in body bags they say were found in a warehouse used by pro-Assad Iranian fighters near the Sayyida Zeinab shrine, a revered site for Shiite Muslims in Damascus. "This place, in the Sayyida Zeinab suburb, was headquarters for Iranian militias.. it appears they died since over two years or one and a half year ago," says a White Helmets member. Since Assad's ouster, a number of mass graves have been uncovered in the country. IMAGES AND SOUNDBITES
