Europe remains on high alert after at least 129 people were killed in the French capital on Friday night at various locations, with the reported mastermind of the attack still at large on Monday. On Sunday, France bombed the Islamic State's de facto headquarters in the Syrian city of Raqqa, in an air raid its Defense Ministry said had been coordinated with American forces.
