The prisoners awaited death as they were locked behind bars in the pool
Islamic terror group ISIS has released harrowing footage appearing to show caged prisoners being lowered into a swimming pool to drown alongside other horrific executions.
The vile group claimed that 16 men were killed in Nineveh, Iraq, after being accused of spying in a set of horrifying killings.
In the first round of executions, five terrified men can be seen being lowered into the water while locked in a cage together.
Minutes later, the cage is lifted, which shows the mean lying motionless on the cage floor.
The barbaric footage even used pricey underwater cameras which were fitted around the swimming pool to capture the scene from below the water.

It then cuts to show four victims locked in an old-looking car in the desert.

The footage then lingers on the exploded car as in languishes in flames.
