ANOTHER BEHEADING VIDEO has been released by Islamic State militants in Iraq.

The six minute video, entitled ‘A Message in Blood’, reportedly shows a group of Kurdish men in orange jumpsuits. One of them is then seen in front of a mosque with three IS militants behind him with guns and he is beheaded.

The militants have warned that others will be killed if Kurdish leaders continue to support the US, Sky News reports.

Earlier, other IS videos appeared to show the mass killing of Syrian soldiers who were taken prisoner when their base was overrun. The jihadists posted grisly video footage on the Internet of scores of bodies heaped in the desert they boasted were those of Syrian soldiers they captured and killed following the seizure of Tabqa air base.

The footage posted by IS showed a close-up of some 20 bodies, but then panned out to show scores more.

Other shots showed men barefoot and dressed only in their underwear walking in line with their hands on their head in surrender, escorted by jihadist gunmen.

In a press conference, US President Barack Obama admitted he still does not have a strategy to fight Islamic State jihadists in Syria.

The chaotic situation on the ground was underlined by the seizing of 43 UN peacekeepers on the Golan Heights by rival Islamist rebels, led by Al-Qaeda affiliate Al-Nusra Front.

They were part of a mission that has monitored an armistice between Syrian and Israeli troops on the strategic plateau for decades. Though Irish troops are stationed in this region as peacekeepers, none of those taken hostage are part of the Irish contingent.

Islamic State militants were also responsible for the killing of US journalist James Foley. He had been held by them for two years before being beheaded ten days ago.
