In a further chilling twist, a young boy aged around four, and appearing to speak with a British accent, also appeared on screen, threatening to kill non-Muslims.
The victims were all shot in the head at point blank range after the well-spoken British sounding terrorist delivered his propaganda rant.
The sickening ten and a half minute video had echoes of those posted by the Isil terrorist dubbed Jihadi John, who was responsible for a string of murders including the beheading of British aid worker Alan Henning.
