Facebook has activated its safety check feature after a suicide attack killed 32 people in the north-eastern Nigerian city of Yola.
The social networking site had been criticised for activating the feature for the attack in Paris on Friday but not for the attack in Beirut the day before.
Before the Paris attack, the feature was only used in natural disasters. The safety check allows people to inform their contacts they are safe
The system was first used earlier this year during the Nepal earthquake.
Facebook boss Mark Zuckerberg announced the Yola Safety Check in a Facebook post:
“We’ve activated Safety Check again after the bombing in Nigeria this evening. After the Paris attacks last week, we made the decision to use Safety Check for more tragic events like this going forward. We’re now working quickly to develop criteria for the new policy and determine when and how this service can be most useful.
Unfortunately, these kinds of events are all too common, so I won’t post about all of them. A loss of human life anywhere is a tragedy, and we’re committed to doing our part to help people in more of these situations.
In times like this, it’s important to remind ourselves that despite the alarming frequency of these terrible events, violence is actually at an all-time low in history and continues to decline.
Deaths from war are lower than ever, murder rates are generally dropping around the world, and — although it’s hard to believe — even terrorist attacks are declining.
Please don’t let a small minority of extremists make you pessimistic about our future.
Every member of our community spreads empathy and understanding on a daily basis. We are all connecting the world together. And if we all do our part, then one day there may no longer be attacks like this.”
