French President Francois Hollande on Saturday put the blame of the deadly terror attacks in Paris on Friday evening on militant group Islamic State. In an impassioned statement to the country, Hollande described the deadly strikes in which at least 127 people have been killed as an "act of war". He said the attacks were co-ordinated, planned and organised from abroad with assistance from inside France. He called the attacks cowardly and said every measure will be taken to fight "the terrorist menace". Hollande also announced that the country will observe three days of mourning.

In a separate development, the Islamic State on Saturday released an undated video of one of its militants threatening France. He is heard saying France "will not live in peace as long as bombing [in Syria] continues". He also called on France's Muslims to carry out attacks in the country if they are unable to travel to Syria themselves.

Reuters reported that French prosecutors have announced a provisional toll of 127 people from the attacks, with 99 people in critical condition.
