Paris was hit by multiple attacks by gunmen and bombers on Friday night local time, with around 140 people feared dead.
The worst single incident occurred at a concert by U.S. band Eagles of Death Metal, where as many as 100 people are believed to have been killed.
To help those in the city let friends and family know they’re safe, Facebook has activated its “Safety Check” feature, a service launched last year to help with communications for those in disaster zones or during incidents like the one in Paris tonight.
Facebook users in the Paris area will have received a message from the service asking them to tap an “I’m safe” button if they’re OK. The service then sends out a notification to all of their friends letting them know they’re fine. An additional “mark safe” button also enables users to mark others as safe.

Addressing the nation on Friday evening, French president Francois Hollande said France would be “merciless” in its response to the attacks and that the tragedy would unite the country.
