Londoner Mohammed Reza Haque is shown beheading a captive in the latest gory video to be posted online by terror group Islamic State (Isis).
Haque, from Bethnal Green – a former bodyguard to jailed hate preacher Anjem Choudary – is being nicknamed "Jihadi John 2" after the infamous Mohammed Emwazi, who beheaded five hostages on video before being killed in an air strike in Syria.
The new video, also filmed in Syria, shows five IS (Daesh) militants, wearing black, standing over five prisoner, who wear orange jumpsuits and are bound and on their knees, as an IS spokesman accuses them of spying for the New Syria Army.
"These apostates who kneel, disbelieved and fell into apostasy, and championed the Crusaders and helped them against Muslims," says the spokesman in Arabic. "They thought they were safe, but God shamed them, and they will be slaughtered by the knife which will slaughter those like them."
Haque, along with the four other IS terrorists, then grabs his victim's hair and beheads him before standing over the body.
It is thought the video was filmed in or near Palmyra, which IS re-took after being forced out in March 2016. It is the second execution video to feature Haque. In January 2016 he was shown shooting a prisoner in the head.
Haque, 36, was filmed at numerous London demonstrations with Choudary, who was jailed in September for inciting support of IS.
In 2011, Haque was filmed chanting "Burn British soldiers, burn in hell," and burning poppies near the Albert Hall on Remembrance Sunday. He was cleared at Belmarsh Magistrates' Court for lack of evidence.
Haque fled to Syria in 2014 via Cyprus and Istanbul despite being watched by MI5 and continued to encourage fellow Muslims to join IS.
Fellow Londoner Mohammed Emwazi – the original "Jihadi John" – beheaded two Britons, David Haines and Alan Henning, as well as three Americans. He was killed in a drone strike in Raqqa in November 2015.
