Residents have been asked to leave their homes at Divis Tower in west Belfast after a security alert was declared over the discovery of a suspicious object.
Police are at the scene and road diversions are in place.
Road users are being asked to avoid the area.
The Police Service of Northern Ireland (PSNI) has said it will continue to issue updates as the situation continues.

“I will continue to stay in contact with police and I hope residents can return home shortly”, he added.
