Bataclan: More than 80 killed in deadliest Paris attack
Warning: This video contains distressing images
Video has emerged of terrified people climbing out from windows at a music venue in central Paris where more than people were killed, in one of several co-ordinated attacks on Friday.
France's President Francois Hollande has described the attacks as an "act of war" committed by so-called Islamic State.
Four gunmen reportedly stormed an Eagles of Death Metal concert at the Bataclan concert hall on Friday evening and began to fire indiscriminately into the crowd, throwing explosives as they went.
One of the attackers is said to have shouted "God is Great" in Arabic during the massacre.
Security forces raided the concert hall and all four individuals were killed. Police say three of the attackers detonated "suicide belts" during the assault, with the final hostage-taker dying in the gunfight.
Some officials described the scene inside the music hall as "carnage."
All members of the popular US rock band are safe and have been accounted for, the Washington Post reports, citing an US official briefed by the Justice Department.
ITV News correspondent Emma Murphy is at the scene and has described the "terrible debris" littered from start to finish with the evidence of the fight to save lives.
