LONDON, Feb 26 (Reuters) - The "Jihadi John" killer who has featured in several Islamic State beheading videos is Mohammed Emwazi, a Briton from a middle class family who grew up in London and graduated from college with a degree in computer programming, the Washington Post newspaper said.
In videos released by Islamic State (IS), the masked, black-clad militant brandishing a knife and speaking with an English accent appears to have carried out the beheadings of hostages including Americans and Britons.
The Washington Post said Emwazi was believed to have traveled to Syria around 2012 and to have later joined IS.
