A massive search was under way Thursday for the wreckage of an EgyptAir plane that plunged into the Mediterranean with 66 people on board, in what the Egyptian authorities said may have been an act of terrorism. Egypt's aviation minister said that while it was too soon to say why the Airbus A320 flying from Paris to Cairo had vanished from radar screens, a "terrorist" attack would be a more likely scenario than a technical failure. The tragedy raised fears of a repeat of the bombing of a Russian passenger jet by the Islamic State (IS) jihadist group over Egypt last October that killed all 224 people on board.
