Hunt on for new ‘Jihadi John’ after five men brutally executed

Intelligence agencies were hunting a new “Jihadi John” Sunday night after an Islamic extremist with a British accent was shown directing the murders of five men accused of spying for the U.K.

In a video released on social media, the masked gunman warned British Prime Minister David Cameron the West could never win in the war against ISIL, while mocking the impact of RAF airstrikes.

At the end of the video a young boy aged around four, who seemed to speak with a British accent, also appeared on screen, threatening to kill non-Muslims.

The victims — who are said to have helped coalition forces by providing information about the whereabouts of ISIL suspects, including the group’s deputy leader — were all shown being shot in the head at point-blank range after the British-sounding terrorist delivered his message of propaganda.

The ten-and-a-half minute video had echoes of those posted by the ISIL terrorist dubbed “Jihadi John,” who was responsible for a string of murders. “Jihadi John,” later identified as 27-year-old Mohamed Emwazi from London, was killed in a U.S. drone strike last November.

MI5 agents were last night working to establish the identity of the new terrorist, amid concern the video might signal the start of a new propaganda campaign following Britain’s decision to join coalition airstrikes against ISIL targets in Syria.

The video began with apparent confessions from the five Arabic men who were wearing orange prisonerstyle jumpsuits. The men claimed to have passed information to the West about prominent ISIL figures.

The video then cut to a desert area where the victims were shown kneeling before five gunmen clad in camouflage clothing and black masks.

Clutching a semi-automatic pistol the terrorist said Cameron was an “imbecile” for thinking RAF airstrikes could have any impact. He said: “How strange it is that we find ourselves today hearing an insignificant leader like you challenge the might of the Islamic State.”

After shouting Allahu akbar, Arabic for God is great, he then opened fire on the victim at his feet, shooting him in the back of the head.

The other gunmen then all opened fire on their victims in a sickening killing spree.
