In Paris, the traditional fireworks display was cancelled to be replaced by a five-minute video performance at the Arc de Triomphe just before midnight. The screening was relayed on screens along the Champs-Elysees.
The city's mayor, Anne Hidalgo, said the video was intended to send "the world the message that Paris is standing, proud of its lifestyle and living together''.
