London Bridge terror attack: Facebook activates safety check tool

Facebook has activated its safety check tool so people can let loved ones know they are safe following the London Bridge terror attack.

The feature allows users to let friends and family know they are OK by marking themselves as “safe”.

It also displays a list of friends who have marked themselves as safe.

The tool was previously used during the terror attack on Westminster in March as well as attacks in Paris and Orlando.

The Met Police have confirmed two separate incidents on London Bridge and in Borough market were part of a terror attack on the capital.

More than one person is believed to have died after a van mowed down pedestrians on London Bridge at 10.08pm.

Armed police also responded to multiple stabbings inside the Southwark Tavern and on Southwark Street near Borough Market.

Prime Minister Theresa May has said that the "terrible incident" is being treated as a "potential act of terrorism".

Scotland Yard warned people to avoid the area and London Bridge station has been closed.
