Intelligence agents in the UK and United States are urgently looking into reports that the Islamic State in Iraq and the Levant (Isil) fighter, whose brutal actions shocked the world, is the ringleader of group of British jihadists who have specialised in hostage taking.The Brit extremists are considered to be some of the most "vicious and callous" militants fighting in that region. Over 500 are known to have made the trek to Syria and Iraq, although around half are thought to have gone back to England. That's around 250 radicalized individuals ready to do evil in the UK.
Based in the Isil stronghold of Raqqa in Syria, ‘John’, is described as a well-educated, intelligent, but highly committed member of the extremist terror group.
Operating closely with two other British born militants, the group have been dubbed ‘The Beatles’, by fellow jihadists because of their nationality.
The UK Telegraph highlights some of those extremists including two 16-year-old twin sisters who went there to become jihad brides.
