Sickening footage appears to show Islamic State militants parading around 250 captured soldiers through the desert in their underwear before they are killed and their bodies piled on the bare earth.
An Islamic State fighter claimed the men were from the Syrian government’s Tabqa air base which extremists seized on Sunday, potentially handing them warplanes, tanks, artillery and ammunition.
The video, which has not been independently verified, is too graphic to be published in full.
It begins by showing dozens of men being marched through the desert wearing only their underwear. It then fades to black, resuming with a pile of bloodied bodies stacked on top of one another.
