LONDON (Reuters) - Investigators believe that The "Jihadi John" masked fighter who fronted Islamic State beheading videos is a British man named Mohammed Emwazi, two U.S. government sources said on Thursday.
He was born in Kuwait and comes from a prosperous family in London, where he grew up and graduated with a computer programming degree, according to the Washington Post.
In videos released by Islamic State (IS), the black-clad militant brandishing a knife and speaking with an English accent appears to have decapitated hostages including Americans, Britons and Syrians.
The Washington Post said Emwazi, who used the videos to threaten the West and taunt leaders such as President Barack Obama and British Prime Minister David Cameron, was believed to have traveled to Syria around 2012 and to have later joined IS.
In each beheading video, he is dressed entirely in black, a balaclava covering all but his eyes and the ridge of his nose. He wears a holster under his left arm.
Hostages gave him the name John as he and other IS Britons had been nicknamed the Beatles. Another was dubbed George.
British government sources and the police refused to confirm or deny the report, citing a live anti-terrorism investigation, a position mirrored by a spokeswoman for Cameron.
