Police in Belfast continued to clash with crowds during a fourth night of violence in the North.
Across the city, missiles, petrol bombs and blast bombs were thrown at PSNI officers, and tyres and vehicles were set alight.
East Belfast was badly affected and some roads were closed - Twadell Ave, Mount Vernon and the Lower Newtownards rd all saw rioting.
Disturbances have been ongoing since police enforced a ruling that an Orange Order parade couldn't march through the Ardoyne on Friday.
The PSNI says they are working with community representatives to restore calm and the DUP has condemned the use of a nail bomb.
Sinn Fein MLA Gerry Kelly says the perpetrators stand alone:
The PSNI are keeping the public informed about disturbances through their Twitter account. These tweets from last night gave an idea of the chaos.
A4 dual carriageway is closed due to a number of tyres having been set on fire. Traffic being diverted through Moygashel.
