A blast bomb has been thrown at police by nationalist rioters and petrol bombs and stones were hurled at them by youths on roof tops of shops in the Ardoyne.
A number of arrests were made as the barrage of missiles continued to hammer into police lines.
Officers warned they would respond with plastic bullets unless the attacks stopped.
Meanwhile, Upper Ardoyne Protestants accused nationalists of trying to provoke a resumption of the daily loyalist protest at Holy Cross school which marred much of last term - but said they would not be drawn back to the demonstration.
The Glenbryn Residents Committee met privately with local political representatives to discuss the street violence.
Community worker Mark Coulter said afterwards: ‘‘There is obvious pressure on this community from elements in the nationalist community to call the protest back on again.
‘‘People are very, very clear that they are not going to be used as political pawns by anyone . We are going to resist the pressure we are coming under to have any sort of protest, and we are calling on people to remain calm.’’
