Almost 50 police officers have been injured during hours of rioting linked to sectarian clashes in north Belfast.

Water cannon was deployed on Sunday night after the officers were attacked with fireworks, petrol bombs and masonry.

Loyalists and republicans attacked police in the Carlisle Circus and Antrim Road areas during significant but localised violence linked to a republican parade.

Four officers were taken to hospital with various injuries. Only one remains in hospital and his injuries are not life-threatening, while 43 other officers were treated for various minor injuries.

At lunchtime on Sunday, a large crowd congregated between the Belfast Orange Hall and Carlisle Circus. A lawful parade had been organised, but police had received no notification of a protest.

When police arrived on the scene some people within the crowd had masked their faces and police observed masonry being broken up by a number of individuals.

Police talked to community representatives with the aim of reducing tension and facilitating the lawful parade.

To allow the parade to pass along its notified route, police moved the crowd back towards Carlisle Circus. Bricks and other missiles were exchanged between parade supporters and protesters as the procession passed through the area, but the most sustained violence was directed at police lines. As the parade dispersed youths also began attacking police in the Antrim Road area.

Trouble continued throughout the night, until the area was reported calm around 2am local time on Monday.
