Video appears to show ISIS fighters executing 'spies' for Britain

The clip shows the shackled prisoners wearing orange jumpsuits before being gunned down in the desert after a British jihadist labels Mr Cameron an "imbecile".

The video then appears to show the murder of the hostages. He said those who want to continue fighting "under the banner of Cameron" should ask themselves: "Do you really think your government will care about you when you come into our hands, or will they abandon you as they have abandoned these spies and those who came before them?"

Isis has released a new video that it says shows the moment five alleged British spies were executed.

ISIS often releases propaganda videos when it suffers setbacks on the battlefield, experts say.

In the latest video the man goes on to say that IS will invade the United Kingdom and rule under Sharia Law.

"In fact David, you are more of an imbecile, only an imbecile would dare to wage war against a land where the law of Allah reigns supreme under the justice and security of the Sharia". "But this time when you lose, your children will inherit your defeats and remember you as the fools who thought they could fight the Islamic State".

It is thought the video - which is ten minutes long and finishes with a child appearing in front of the camera - was filmed in the Syrian city of Raqqa.

The boy says: 'We will kill them over there'.

The fanatic, real name Mohammed Emwazi, was filmed executing British aid workers David Haines and Alan Henning, American journalists Steven Sotloff and James Foley, American aid worker Peter Kassig and Japanese journalist Kenji Goto.

The clip was uploaded a month after RAF jets pounded ISIS targets in Syria after Parliament approved military action against the terror group.

It comes days after Mr Cameron promised to crack down on IS sympathisers, stressing in a New Year's message that all Britons should have "loyalty" to their country. He has yet to comment publicly on the killings.

The ISIS terror group threatened Britain in an Internet video Sunday showing the killing of five "spies" after a child vow to "kill kuffar" (non-believers).
