Isis executes prisoners by drowning them in a cage and blowing them up with grenade launchers

Isis has released disturbing footage of their latest string of executions, one of which involves five prisoners being locked in a cage and then drowned in a swimming pool.

The terror group claims it has executed 16 men who it accuses of spying.

The alleged spies were separated into three groups, with each group subjected to a different method of execution.

 

Cowardly: Moments later a masked Islamic State jihadi appears carrying a huge grenade missile launcher

 

Fired from close range: The grenade launcher is fired towards the vehicle, causing it to burst into flames

 

Smoke: The car is seen in flames meaning the badly injured victims are likely to have bued to death

In another clip, prisoners are driven out into the desert

One group of five men are locked in a cage which is then lowered into a swimming pool. Underwater cameras capture their last moments alive.

In another piece of footage, four prisoners are driven out to the desert and left in the car. They are then blown up by a militant wielding a grenade launcher.

A third clip shows six prisoners kneeling and being forced to admit to their alleged crimes before explosives tied round their necks are detonated.

The news comes as the terror group was accused of crucifying two children for eating during Ramadan.

Militants reportedly fastened the children to poles in Mayadin, Syria, with placards around their necks announcing their supposed ‘crime".
