Facebook activated its safety check feature after the suicide attack on 17 November that killed 34 and injured 80 in the north-eastern Nigerian city of Yola, reports the BBC.

The social networking site had been criticised for activating the feature after the attack on Paris, but not for other atrocities.

The safety check allows people to inform their contacts that they are safe.

One Yola resident who used the feature, Maulud Usman, said he felt the criticism had been heard: “Boko Haram has been bombing us in north-eastern Nigeria for years, killing thousands of people, yet Facebook didn’t deem it fit to activate the safety check. I’m happy [Facebook boss, Mark Zuckerberg] listened to our cries.”
