On Friday, Paris was rocked by multiple terror attacks.
Reports are saying over 100 people have been killed in a series of assaults, including a hostage situation at Le Bataclan concert hall, explosions during a soccer game at Stade de France, and other shootings.
France's president François Hollande has closed the nation's borders and issued a state of emergency. Police are encouraging civilians to stay off the streets.
In the wake of the terrifying tragedy, Parisian residents are using social media to offer assistance to anyone in the city who doesn't speak French.
One Twitter user shared:
"Porte ouverte" translates to "open door" in English, and that's exactly what the capital's residents are embracing.
A website called porteouverte.eu has been set up to help anyone who's stranded to seek shelter from people in the city who's graciously offered to share their living space.
If non-French speakers in the area search the hashtag online, they'll be able to find and DM users who are willing to let anyone in need of assistance into their homes.
