Facebook has activated its Safety Check feature in the wake of the terrorist atrocities in Brussels this morning (March 22).
The feature allows users to easily tell their friends that they are safe during a disaster, with Facebook able to guess if they are in the area.
Once they mark themselves safe, it will appear to all their friends.
It has been activated after Tuesday's attacks in Brussels, which have left at least 26 people dead and over 100 people injured. Belgian prime minister Charles Michel has confirmed an explosion at Zaventem airport was a suicide bomb attack.
Safety Check was first used during a terrorist atrocity in the Paris attacks in November, having previously only been utilised for natural disasters.
Following this, it has drawn controversy for disregarding attacks in non-Western or developing countries.
It has since been used in the wake of attacks in Nigeria and Turkey.
