IS executioner Jihadi John shows his face, promises return to UK to cut off heads - Islamic State (IS) killer Jihadi John has appeared unmasked in a 17-second video clip for the first time and has threatened to return to the United Kingdom.

The notorious IS executioner has released a video, in which he has identified himself as Mohammed Emwazi. Besides vowing to 'carry on cutting heads,' Jihadi John, said that he will 'go back to Britain alongside the Khalifa,' the head of the IS in Iraq and Levant, according to a report by Daily Mail.

Maybe the video was shot on a cell phone about 2 months ago, close to the IS-held town of eir Ezzor in south-east Asia. Jihadi John could be seen standing in front of a grenade launcher on a flat-bed truck. He looks at the camera before looking away into the desert, according to the report.

The video was unofficially acquired by rebel fighters of the Free Syrian Army, who sent it to one of their colleagues, Abu Rashid, in the Bulgarian capital Sofia.
