A senior Northern Ireland police officer has said there will be "significant arrests" of those involved in rioting in Belfast.
Up to six shots were fired in a third night of violence in north Belfast on Tuesday, during confronations between nationalist protestors and riot police, the BBC reports.
Petrol bombs and a pipe bomb were also thrown by nationalist rioters in the Ardoyne area, and about 100 officers used water cannon and baton rounds.
On Wednesday, Assistant Chief Constable Duncan McCausland said children as young as 10 were involved in the violence.
He said as well as throwing stones and petrol bombs, young children were being used as shields by "sinister elements" organising the riots behind them.
Assistant Chief Constable McCausland said police had hours of video footage from before the violence started and would use it to identify the rioters.
