ISIS taunts David Cameron and threatens Britain in execution video

The Islamic State group has released a new execution video that mocks British Prime Minister David Cameron and threatens Britain. The video footage shows five spies executed on the groups that they coordinated with the international coalition fighting the group in Syria and Iraq.

According to the SITE Intelligence Group, the video featured confession of the five men on espionage. They came from Raqqa which is considered the capital of the self-declared extremists "caliphate" spanning Iraq and Russia. The five men were also dressed in orange. They were prompted to kneel before they got shot in the head. However, the confessions on the video were not enough to identify the countries the five men worked for. One of them did say something about a US-led international coalition against IS.

"We are aware of the video and are examining the content," the British foreign office said in a statement according to 9news.

Furthermore, the footage also revealed a member of the group speaking with a British accent. The person was brandishing a gun mocking Cameron including the RAF’s bombing campaign against the group in Syria and Iraq.

"This is a message to David Cameron," said one of the gunmen.

"How strange it is that we find ourselves today hearing an insignificant leader like you challenge the might of the Islamic State."

It can be noted that British warplanes targeted extremists in Syria as well on top of attacking IS positions in Iraq.

"Only an imbecile would dare to wage war against a land where the law of Allah reigns supreme and where the people live under the justice and security of sharia or Islamic law," added the fighter.

"We will continue to wage jihad... and one day invade your land, where we will rule by the sharia."

Shashank Joshi, a senior research fellow at the Royal United Services Institute (RUSI), said that the video can be considerd IS's attemp to divert attention from the group's current problems like losing Ramadi in Iraq.

"I think there is an overall sense in which they have had relatively few successes in the past few weeks," said Joshi via Belfast Telegraph.

"They have been pushed back and these videos are a method to try and maintain support."
