Elite police commandos launched an assault on the venue and killed two gunmen.
One official described "carnage" inside the building, saying the attackers had tossed explosives at the hostages.
Witnesses outside the venue in the 11th arrondissement reported hearing five successive explosions followed by gunshots.
