LONDON — The Islamic State released a new video purporting to show the killing of five hostages who the militant group said were spying for Britain inSyria.
In the footage released online Sunday, a masked man with a British accent calls British Prime Minister David Cameron a "slave of the White House," and "mule of the Jews."
"Only an imbecile would dare to wage war against a land where the law of Allah reigns supreme," he says. "The Islamic State, our country, is here to stay. And we will continue to wage jihad, break borders, and one day invade your land, where we will rule by the Shariah."
One hostage says he was asked to locate two British members of the extremist group, also known as ISIL or ISIS, and photograph a building being used by the militants as a courthouse. Britain began launching airstrikes against ISIL positions in Syria last month. France, Russia and the United States are also bombing militants in Syria.
One of the condemned men appeals to other so-called spies to turn themselves in, saying "the door to repentance is open." Another hostage says "Don't let them fool you like they fooled us."
The video, which cannot be independently verified by USA TODAY, then shows the hostages, wearing orange jumpsuits, being shot in the head by masked militants.
An English-speaking young boy wearing military-style clothes points into the distance and says: "We are going to go kill the kafir (unbelievers) over there."
The video bears similarities to previous ISIL execution videos featuring Mohammed Emwazi, a London-raised militant also known as "Jihadi John," who beheaded Western hostages. Emwazi was killed by a U.S. drone strike in Syria in November.
Some media are calling the militant in the latest video, who is holding a gun, "the new Jihadi John."
Britain's Foreign Office said it is aware of the video and is examining its content.
