THE Crumlin Road at Ardoyne in north Belfast is closed after a suspected nail bomb device was thrown at a police vehicle.
The device was thrown while police were observing a white line loyalist protest.
The PSNI say the device was thrown from the nationalist Brompton Park area of Ardoyne.
The device did explode but no one was injured.
Loyalists claim it was thrown from the direction of a local bookmaker’s shop in the nationalist area.
Army technical officers have been tasked to deal with the device.
The road is closed between Tennent Street and Twadell Avenue and motorists are asked to avoid the area.
