Barbaric Islamic State terrorists have released an horrific video of captured soldiers being led to their deaths.
The 15 soldiers in dark overalls kneel in front of IS militants and, one by one, large knives are taken out of a box.
The beheadings are off camera but over a dozen decapitated heads are left on the ground by the bodies.
Footage also showed Peter Kassig, 26, captured last year while providing aid to Syrian people, wearing an orange jumpsuit and kneeling in front a knife-wielding hooded man.
The killer, who had a London accent and is known as Jihadi John, said Muslim extremists would kill other US citizens “on your street”.
