A round-up of the violence which broke oiut around the Six Counties following the PSNI attack on the Ardoyne protest.
MONDAY

The worst of the violence that occurred on the Twelfth took place in the north of the city. The fiercest rioting was in Ardoyne and broke out after the PSNI forced through an Orange Order march having spent three hours clearing residents from the road where they had staged a sit-down protest. Riot police then engaged nationalist youths.
Around 70 plastic bullets were fired and water cannon were deployed.
A female police officer was struck with a rock that the PSNI claimed had been dropped from a height. Other reports suggested that it was water cannon which had dislodged pieces of masonry from a shopfront.
Earlier in the day two cars were hijacked in the Oldpark area. One of the vehicles was abandoned in Alliance Avenue in Ardoyne and sparked an alert.
Claims that a member of the Orange Order was struck by a stone were later denied.
