Sickening new Isis video shows caged prisoners lowered into a swimming pool and drowned, shot with an RPG and blown up with explosive-filled 'necklaces'

Footage shows five men being drowned in a pool in the Isis stronghold Mosul

Another group are shot with a grenade launcher while locked in an old car

Final sequence shows seven prisoners being chained together with explosive necklaces, which are then detonated

Vile jihadis fighting for the Islamic State in Iraq have brutally murdered five prisoners by locking them in a metal cage and lowering them into a swimming pool. The sickening seven minute long video uses expensive underwater cameras to film the terrified men as they sink below the surface with no hope of escape.

Shortly afterwards the cage is lifted back out of the water, with the dying men - who are understood to have been accused of spying - seen foaming at the mouth as they lie motionless on the floor of the cage, piled on top of one another.

Elsewhere in the video, Isis militants are filmed brutally killing prisoners by locking them in a car and shooting them with a grenade launcher, while another group of jihadis chain a set of prisoners together with explosive necklaces which are then detonated.

This is disheartening!!!
