French President Francois Hollande says France is 'at war' against terrorism by the Islamic State group.
Hollande says he wants "large coalition" working together against IS militants to destroy a group that threatens the whole world and "commits massacres" in the Mideast.
Hollande says "we are at war." He was speaking in a televised address Wednesday after a seven-hour police siege on an apartment north of Paris where police suspected the mastermind of the deadly Paris attacks might have been.
He says the French aircraft carrier Charles de Gaulle just left to help French military operations in Syria against IS.
