People gathered at vigils worldwide after at least 120 people were killed and eight assailants died in a coordinated terror attack at multiple sites in Paris.
At one point, more than 100 people were taken hostage at a concert hall, leading to a police raid on the venue.
The death toll is expected to rise as France takes stock of the carnage Saturday morning.
Meanwhile, mourners have been creating makeshift vigils at embassies and public areas across the world.
