As the city was gripped by chaos following a string of attacks that left dozens dead, people in Paris took to social media to find and offer refuge on Friday night.
The Twitter hashtag #porteouverte, which means "open door" in English, was being used to offer shelter as authorities urged people to evacuate the streets. The hashtag trended globally, with more than 400,000 tweets using it in the few hours after its creation.
"This account will be used for tweeting and retweeting places to stay safe tonight," said a post from @PorteOuverteFRA, a Twitter handle opened within hours of the attacks.
