Four people were arrested in the North overnight on a 6th night of disorder.
The PSNI says it was calmer than previous nights - with no police officers injured and no water cannon deployed.
However, officers in Newtonabbey near Belfast, Co. Antrim were targeted by youths throwing missiles and officers recovered 6 petrol bombs.
The unrest started over the Parades Commission's decision to ban the Orange Order from marching in the Ardoyne.
The Commission will today rule on a request for a fresh march in the republican area this weekend.
300 extra police officers have been drafted in from the UK to assist the PSNI in Belfast as it's anticipated riots may escalate this weekend.
The police have once again been using Twitter to provide updates about security concerns.
Correction to last, Police received a report a petrol bomb had been thrown in area of Oldpark Rd and a car set alight earlier this evening.
