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.
Filmed in the ISIS stronghold of Mosul, 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.
