Paris residents were using the hashtag #PorteOuverte — French for "open door" — on Twitter to offer safe haven to strangers stranded after a string of deadly attacks Friday night.
The hashtag was trending worldwide on Twitter as Parisians tweeted in French and English to let people know where there was room for them to take shelter.
Twitter users in other countries also began using the hashtag to share their delight that social media was being used for a good cause.
At least six attacks across the city sent Paris into chaos as explosions and shootings were reported at a sold-out rock concert, cafes, and outside a soccer match. The death toll in the attacks could exceed 120, according to Paris Prosecutor Francois Molins.
