DHAKA: The Islamic State (IS) terrorist group on Sunday released a video showing the simultaneous beheadings of at least 15 men described as Syrian military personnel.

In the highly choreographed sequence, IS militants march the prisoners by a wooden box of long military knives, each taking one as they pass, before forcing their victims to kneel in a line and decapitating them.

The same video showed what the group said was the beheading of US aid worker Peter Kassig as a warning to the United States.

‘This is Peter Edward Kassig, a US citizen of your country,’ said a black-militant wearing a balaclava, the same outfit worn by the man who beheaded two American journalists and two British aid workers in earlier videos.
