London, Feb 26: The burly masked Islamic State (IS) terrorist known as 'Jihadi John' seen in gruesome videos of beheadings of Western hostages was today named as a Kuwait- born Londoner.
Mohammed Emwazi, the 26-year-old ruthless killer, has featured in a series of chilling videos of executions of hostages, some of whom he kills himself.
Emwazi, who holds a degree in computer programming, is shown speaking with a British accent and dressed in a black robe with a black balaclava covering all but his eyes and top of his nose. He was also known to UK security services who chose not to disclose his identity earlier for operational reasons, the BBC reported.
Emwazi first appeared in a video in August 2014, when he apparently killed the American journalist James Foley.
He was later thought to have been pictured in the videos of the beheadings of US journalist Steven Sotloff, British aid worker David Haines, British taxi driver Alan Henning, and American aid worker Abdul-Rahman Kassig, also known as Peter.
Following Henning's beheading last year, Prime Minister David Cameron stepped up the hunt for the executioner.

The Washington Post reported that Emwazi was a Briton and belonged to a well-to-do family who grew up in West London. He is believed to have travelled to Syria around 2012 and to have later joined the IS, the group whose barbarity he has come to symbolise, it said.
Speaking with a British accent, he taunted and threatened Western powers before holding his knife to the hostages' necks, appearing to start to cutting before the film stops.
Last month, the militant appeared in a video with the Japanese hostages Haruna Yukawa and Kenji Goto, shortly before they were killed. British police declined to officially comment on the reports.
Commander Richard Walton, head of the Metropolitan Police's Counter Terrorism Command, said: "We have previously asked media outlets not to speculate about the details of our investigation on the basis that life is at risk.
"We are not going to confirm the identity of anyone at this stage or give an update on the progress of this live counter-terrorism investigation."
