Petrol bombs thrown at police in Ardoyne
Police have used water cannon on rioters in the Catholic Ardoyne area in north Belfast.
Petrol bombs have been thrown at police. Some of the rioters have also pushed a burning car towards police lines.
Earlier, 24 Orange Order marchers completed a contentious parade past the area.
Some nationalists object to the parade which marks William III's victory at the Battle of the Boyne in 1690.
After the burning car was extinguished, police decided it would be safe for a planned protest parade by The Greater Ardoyne Residents' Collective, to go ahead.
Earlier, police said the Orange Order parade had passed "peacefully" and "in accordance with the Parades Commission determination".
Thousands of Orangemen, often accompanied by flute bands, stage a major demonstration through Belfast every year.
They weave through the city's streets to gather in a field where they hear religious addresses.
Most parades pass off without incident, but as each branch - or individual lodge separates from the main group to return to their own areas in the evening, there can be trouble.
The representatives of three Orange lodges, carrying three banners, were escorted by riot police as they walked past Ardoyne.
The marchers were completing a controversial parade within a deadline set by the Parades Commission.
There was some shouting from nationalist protestors as the small group of marchers went past.
Hundreds of loyalists were waiting to welcome them when they had passed the contentious area.
The marchers had been taken to north Belfast by bus to meet a 16:00BST deadline set by the Parades Commission.
Orangemen say it was a peaceful solution to allow them to complete their return parade from the main celebrations to their Orange halls in north Belfast.
Meanwhile in the mainly nationalist village of Crumlin, in County Antrim, a Twelfth of July Orange parade complied with a Parades Commission ruling and all lodges except the local ones took an alternative route to a dispersal point.
Only the nine local district lodges and five bands are taking the full return route back through the village.
Elsewhere, police in Craigavon advised motorists to avoid the Drumbeg estate area following the hijacking of a bus.
All bus services between Lurgan and Craigavon were diverted past all estates.
