Police in west Belfast have come under attack again during another night of sporadic rioting involving teenagers as young as 13.
Petrol bombs, bottles and stones were thrown at PSNI officers during violence involving youths from the Protestant Springmartin area and the Catholic New Barnsley estate.
The two sides threw missiles at each other before community representatives eventually managed to restore calm.
Four people were arrested, but some local residents have accused the police of standing by and not doing enough to intervene.
The PSNI says it has to make a judgement about whether intervention would escalate the situation and is appealing to parents to exercise more control over their children.
