LONDON — British Prime Minister David Cameron on Friday lauded a U.S. drone strike targeting “Jihadi John,” the masked Islamic State executioner who came to symbolize its brutality. But Cameron said there was no certainty that the British extremist was dead.

The Pentagon said the attack was carried out Thursday, and that officials are still working to determine whether the strike killed the London-raised militant, Mohammed Emwazi.
