Police have renewed an appeal for help in identifying those involved in violence at the "Tour of the North" Orange march in north Belfast on June 17th.
Nationalist protesters stoned loyalist marchers and supporters as they passed a flashpoint at Ardoyne on their way back to Ballysillan.
Up to 20 people, including police officers, were hurt as petrol bombs, stones, bricks, golf balls and bottles were thrown during about 30 minutes of sporadic violence. Police are seeking the help of local people in Ardoyne to identify some teenagers who were involved in the trouble and were caught on CCTV.
The violence flared despite the efforts of many protest marshals on the nationalist side to stop the stone-throwers.
In another Orange march-related incident in east Belfast at the weekend, two children were hurt as stone-throwers attacked cars in the Markets area of the city.
The children were taken to hospital for treatment after the windows of their car were broken. However, they were not seriously injured.
Witnesses said a crowd of youths, some armed with hurleys, attacked several cars.
The driver of the car - who did not want to be identified - said it had been a frightening experience. He told the BBC: "Stones bounced off the sides of the car and the windows smashed. My 10-year-old was sitting at the window that was smashed and my two-year-old was sitting in the back behind her.
"The glass ended up going into the back as well and the whole car was covered in glass." The cars were being driven by people leaving the mini-Twelfth parade in east Belfast.
There was a major security presence for the march, particularly at the flashpoint area near Short Strand, but it passed off peacefully.
