London Mayor wants 'jihadi John' killed

Boris Johnson has said he wants the reportedly English jihadist who beheaded an American journalist to be killed in a bomb attack, and has joined the growing calls for Britons fighting abroad to be stripped of their citizenship.

The Mayor of London said Britain must take on Islamic State (IS) and “try to close it down now”, warning that doing nothing would mean a “tide of terror will eventually lap at our own front door”.
