Founder of Facebook, Mark Zuckerberg took to his Facebook wall to announce that they have activated the safety check on their site following the bomb blast in Yola, Adamawa state yesterday.

Facebook came under fire for a perceived Western bias when it activated Safety Check after the Paris attacks, with critics noting that terrorist attacks in the Middle East, Africa, and Asia hadn't previously warranted its deployment. The safety check enables Facebook users announce that they are still alive after a mishap in any troubled zone.
