'Jihadi John' threatens to return to Britain to 'carry on cutting off heads'

London

 The IS executioner known as "Jihadi John" has been filmed saying he will return to Britain to continue "cutting off heads".

 The terrorist, who has been in hiding since he was named as 27-year-old Londoner Mohammad Emwazi, had previously been caught on film in January.

 In a one minute and 17 second video, he is seen wearing a black hood with his face uncovered for the first time on camera.

 He is heard threatening to return to the UK with the leader of IS ("Khalifa") to kill non-Muslims ("kuffar").

 The new footage, released by The Daily Mail, is believed to have been taken in south-east Syria two months ago.

 The footage was captured in secret on a mobile phone by rebel fighters in the Free Syrian Army.

 An audio clip, which accompanied the video, includes a man with a British accent saying: "I am Mohammed Emwazi. I will soon go back to Britain with the Khalifa... We will kill the kuffar... I will carry on cutting heads."

 Emwazi is believed to be responsible for the beheadings of at least seven Western hostages, including Britons David Haines and Alan Henning.

 He was also seen in another video taking part in the execution of 17 Syrian soldiers.
