ISIS force brainwashed 'cubs of the caliphate' to shoot prisoners in back of head in sickening new video

Young ISIS recruits brandishing handguns shoot prisoners in the back of the head in a brutal new execution video from the terror group.

The two boys - both dressed in black - force their captives to kneel in front of them in front of a building in Afghanistan.

Sickening footage shows them brutally pulling back the heads of the two terrified men, accused of being spies, before the younger of the two jihadists starts ranting at the camera.

The 'cubs of the caliphates' - a name given to youngsters who have been brainwashed with ISIS ideologies and trained to kill - then point their guns at the hostages before shooting them.

Savage footage also shows three more men murdered - this time by four heavily-armed adults standing next to an ISIS flag.

The so-called Islamic State has released several videos showing young children carrying out brutal executions of adults and training with weapons as they pledge allegiance to ISIS.

Earlier this year a video emerged of a toddler shooting a prisoner at point blank range while standing in a kids ball pit.

Children were seen executing three 'apostates' - Kurdish fighters - in Syria.

Kids across Syria - many no older than 13 - are being torn away from their families and brainwashed by Islamic State thugs .

The warped training camps involve a rigorous regime of early morning wake-ups, study and physical exercise.

Last month it emerged that the head of ISIS in Afghanistan was killed in a raid carried out by Afghan and US special forces.

Abdul Hasib died during an attack by 50 US special forces and 40 Afghan commandos overnight on April 27, President Ashraf Ghani said.

A statement by United States Forces said the raid also killed several other high-ranking members of the organisation along with 35 fighters.

Hasib took over as leader of ISIS-K, an ISIS affiliate in Afghanistan, last year after predecessor Hafiz Saeed Khan was killed by a US drone strike.

Hasib was responsible for directing the Kabul National Military Hospital attack on March 8 which killed more than 100 Afghan civilians, the statement said.

He was also allegedly responsible for beheading tribal elders in front of their families and kidnapping women and girls before forcing them to marry his fighters.
