In Syrian war

one civilians in all were murdered in the single coldblooded incident in 2013. One by one, the blindfolded detainees were brought to the edge of a freshly dug pit in the Damascus suburb of Tadamon and systematically shot. The bodies, piled one on top of the other, were later set on fire.
Footage of the massacre, carried out by Syrian militia members loyal to Bashar Assad’s regime, emerged only in April this year following an expose by the UK’s Guardian newspaper and the online New Lines Magazine.
The amateur video, taken by the killers themselves, was discovered by a militia recruit in the laptop of one of his seniors. Sickened by what he had seen, the rookie passed the video on to researchers, who later confronted one of the killers identified in the footage.
