Facebook has launched its safety check feature Ankara so users can let friends and family know they’re OK following this evening’s bombing, which killed dozens and injured many more in the heart of Turkey’s capital.

The Turkey debut of Facebook’s emergency contact system may find limited use in practice because social media sites have been blocked amidst government-imposed media restrictions in the country.

The feature, launched in October 2014, originally intended for use in natural disaster scenarios, was subsequently deployed in terror incidents beginning with the November 2015 Paris attacks.
