A gang of youths attacked police in Dunmurry with petrol bombs on Saturday night.
At around 9.20pm a group of up to 30 youths threw petrol bombs at police who were attending a disturbance at Stewartstown Road on the outskirts of Belfast.
Police said the youths were dispersed quickly and there were no reports of injuries.
Lagan Valley Alliance MLA Trevor Lunn condemned the incident and said it bore the hallmarks of an organised dissident republican attack.
He said: “It sounds like dissident republicans to me. How else would petrol bombs have been used? It sounds like an organised attack. We keep hearing that these sorts of gatherings are being organised through social networking sites.”
Sinn Fein Lisburn councillor Angela Nelson condemned the attack, but blamed it on anti-social behaviour. “This is definitely not sectarian. I would say it was kids. I was shocked to hear the news because there has been so much peace in the area of late. There has been no anti-social behaviour and no joyriding in the area,” she said.
