PARIS (Reuters) - French prosecutors said on Saturday that three coordinated teams of gunmen and suicide bombers carried out a wave of attacks across Paris that killed 129 people in what President Francois Hollande called an "act of war" by Islamic State.

Hollande declared a state of emergency, ordering police and troops into the streets, and set three days of official mourning as a stunned nation sought to comprehend the simultaneous assault on restaurants, a concert hall and the national football stadium on a busy Friday evening.
