Something unexpected happened to ISIS captives at point of death(Photos)

A new ‘execution' video features rebel Syrian fighters forcing ISIS captives to kneel in the dirt at gunpoint - only for them to do something completely unexpected.The footage opens with captives being led along a dusty road in orange jumpsuits.
The captives are then forced to kneel in the dirt while the members of the al-Shamiyya Front (a coalition of northern Aleppo-based rebel factions) proudly display their pistols.They then point the weapons at the back of the militants’ heads.
