US Airstrike Targets Jihadi John

"Jihadi John," the jeering, sadistic masked mouthpiece of ISIS, may have been killed in a coalition airstrike in the northern Syrian city of Raqqa.

Secretary of State John Kerry and Prime Minister David Cameron of Britain said on Friday that they did not yet know the outcome of an airstrike the American military launched on Thursday to kill Mohammed Emwazi, the Islamic State’s most notorious executioner.
