Islamic State militants 'behead Kurdish man' in Iraq
Islamic State has released a video appearing to show the beheading of a Kurdish man as a warning to forces fighting the group in northern Iraq.
The video, entitled a Message in Blood, shows several men in orange jumpsuits said to be captured Kurdish fighters.
The victim is then seen kneeling near a mosque in the IS-held city of Mosul before he is beheaded.
The jihadists warn that others will be killed if Kurdish leaders continue to back the US.
Meanwhile, US President Barack Obama admitted that he still did not have a strategy to fight Islamic State jihadists in Syria, as the militants boasted they had executed scores of Syrian troops - the latest in a string of atrocities that have shocked the world.
