Police attacked as Northern Irish violence spreads to another town

PORTADOWN, Northern Ireland (Reuters) -Rioters attacked police with petrol bombs, rocks and fireworks in the Northern Irish town of Portadown on Thursday, a Reuters witness said, as a fourth night of anti-immigrant violence moved to a different part of the British-run province. One of a number of anti-immigration protests on Thursday was held in Portadown, 50 kilometres from the capital Belfast. Other protests passed off without major incident, including in Ballymena, the primary flashpoint of the first two nights of more intense violence, local media reported.
