JUST IN: Netanyahu says the attacker aboard the flydubai flight underwent "Islamist radicalization" and intended to crash the plane with everyone on board. "As time passes, the picture is becoming clearer: Yaniv and his hero friends prevented catastrophe on the scale of 9/11." The prime minister says investigators are now working to determine whether the attacker was sent by someone else, warning: "Whoever sent him will pay a high price." The Omani co-pilot is accused of stabbing the captain and sending the Tel Aviv-bound jet into a dangerous dive before passengers and others aboard intervened. The suspect remains in custody as authorities investigate his motive and whether he acted alone. ▻
