Jihadi John and Isil ‘trying to inspire terrorist cult of misfits and mentally ill to commit atrocities’

Mohammed Emwazi and his Isil murderers are creating a terrorist “cult” of misfits and mentally ill to commit atrocities around the world and film and broadcast them, the country’s most senior counter-terrorism officer has warned.

Metropolitan Police assistant commissioner Mark Rowley said the terror threat facing the UK had “fundamentally” changed and showed no signs of lessening.

He warned the days of “tight secret cells” of terrorists had been replaced with Isil’s ability to inspire anyone, anywhere to kill in its name.

Speaking in the wake of London-based Emwazi being named as the Islamic State terrorist known as Jihadi John, he said that “uncertainty” had made it far more difficult for police and the security services to monitor targets.
