Facebook activates Safety Check in Nigeria following bombing

For the second time in a week, users can ensure their loved ones are safe following a terror attack via the social network

Facebook has turned on its Safety Check feature for users in Nigeria, following a bombing in the city of Yola on Tuesday.

Safety Check allows any user of the site who is present in an area affected by a disaster or attack to mark that they are safe. Its use in Nigeria is only the fifth time that the feature has been activated, and the second time that it has been enabled after a terrorist attack. The first was during Friday's shootings in Paris.
