Video: ISIS militants are thrown to their deaths and shot

WARNING GRAPHIC CONTENT: The Iraqi govement is investigating an unverified video which shows an IS extremist being thrown off a cliff as the govement tries to prevent revenge attacks

The Iraqi govement is investigating gruesome footage which allegedly shows troops throwing captured Islamic State militants to their deaths before shooting them on the ground.

Graphic video, allegedly filmed in Mosul, seemingly shows soldiers beating extremists before one detainee is chucked off a cliff.

The detained man is seen landing next to a motionless body at the foot of the perch before troops open fire in an execution style reminiscent of IS.

The murderous terror group have previously filmed killings of people they ruled were guilty of being homosexual by throwing them off high buildings.
