The Islamic State (IS) group threatened to invade Britain in a new video on Sunday, according to the Syrian Observatory for Human Rights
In the video, an unnamed IS executioner with British accent called British Prime Minister David Cameron an “imbecile”, before executing five men who appeared shackled and dressed in orange boiler suits. They were accused of spying against the IS for Britain.
The video was allegedly filmed in Raqqa, the de facto “capital” of the terrorist group in northern Syria.
Last month, Cameron said Britain has a moral and military duty to attack the IS in Syria, while the British military has already extended an air campaign against the group from Iraq to Syria.
Meanwhile, the UK’s security and intelligence agencies are examining the video to identify a man and young boy with British accents, BBC reported.
The authorities will also be carrying out voice-print analysis to match what is heard against individuals known to have travelled to Iraq and Syria.
