France's President Francois Hollande has blamed the Islamic State (IS) for the massacre of more than 120 people in a series of attacks in Paris. In an emotional address to the nation he said the country had come under attack by a terrorist army.

Hollande described the coordinated spree of shootings and bombings that engulfed Paris on 13 November as "an act of war". "It was an act of war committed by a terrorist army, Daesh [another name for Isis] against the values that we defend and embody, a free country," the president said.

Hollande said the attacks were organised and prepared outside the country and executed with the help from accomplices inside France. He has declared three days of national mourning. "The country is in pain," he said. He woved France is to react strongly and will eventually "triumph over barbarism".

At least 128 people were killed and more than 250 people injured, including 100 currently in critical condition, in attacks at six different locations in the capital. Authorities said eight attackers were killed, including seven who blew themselves up, and they are hunting possible accomplices.
