Islamic State militants threaten to cut off Barack Obama’s head and turn the U.S. into a Muslim province in the latest gruesome video to emerge from their self-styled caliphate.

‘Know, oh Obama, that will reach America,’ proclaims a black-clad militant. ‘Know also that we will cut off your head in the White House, and transform America into a Muslim Province.’

The militant delivers his biblical-sounding tirade flanked by comrades and standing over a kneeling Kurdish soldier who, in a gruesome climax to the video, has his head cut off.
