By BI: Islamic State jihadists have ratcheted up their savagery with a video showing an executioner hacking off a prisoner’s hand and foot while he is tied to a cross. In just-released footage, the knife-wielding ISIS jihadist is seen slicing off the man’s limbs as he hangs helplessly from the wooden stake.

UK Daily Mail   After the barbaric attack, the video then zooms in to show the man’s corpse – dressed in an orange Guantanamo-style jumpsuit – hanging lifelessly in the middle of the desert.

Chillingly, the four-minute video even includes a ‘confession’ with the man before he is executed. The terror group claims it carried out the brutal killing because the man, believed to be from Iraq, was working as a spy. The disturbing film (below) is entitled ‘Deterring the Spies 1′, suggesting it is the first instalment in a series of similar executions which are due to take place.

First the right hand, then the left foot goes

Aymenn Jawad Al-Tamimi, a research fellow at the Middle East forum, said the jihadist speaking on the video mentions four other ‘spies’ who are still due to be tried and executed by the militants. One of them allegedly facilitated contact with the Peshmerga, the militant claims.

A quote from the Qur’an is then shown. It reads: ‘The penalty for those who wage war against Allah and His Messenger… is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land.’

In the most haunting scene, the killer – who is not wearing a mask – then swings his hunting knife towards the man’s right hand, before attacking the man’s left foot, as he cries out in pain.

The video comes just hours after ISIS released images showing a prisoner being decapitated, in a sickening echo of the executions carried out by British militant Jihadi John.
