Violence flared for the fourth night running in Northern Ireland, hours after politicians and Church leaders held talks in a bid to quell a row over the flying of the British flag.

After three nights of rioting and attacks on police, Northern Ireland’s chief police officer Matt Baggott said 52 officers had been injured, but he warned his force would deal firmly with the violence for as long as it was necessary.

“You may be assured there will be sufficient resources in the event of more disorder for however long is necessary,” said Baggott, the PSNI chief constable.

But as darkness fell yesterday, a mob gathered and hurled steel barriers, bricks, fireworks and bottles at officers patrolling Castlereagh Street in the east of the city. Unrest was also reported on Mountpottinger Road and Beersbridge Road.

Police used water cannons and fired baton rounds in Belfast on Saturday as they confronted more than 100 loyalist protesters who were throwing fireworks and bricks. Officers reported coming under gunfire. A 38-year-old man was arrested on suspicion of attempted murder.

The discussions aimed at ending the violence took place at a Belfast church, but Robin Newton of the Democratic Unionist Party, said lack of engagement from protest organisers was making it difficult to see an end to the unrest.

“We have to find a way out of this, but how we do it I don’t know,” he admitted.

The rioting on Saturday followed a largely peaceful demonstration by more than 1,000 people outside Belfast city hall against the city council’s decision last month to limit the days it flies the British flag, or Union flag, each year.

The ruling on December 3 was viewed by pro-British loyalist groups as a concession too far to republicans who want Northern Ireland to be part of Ireland.

Protesters immediately took to the streets and there have been on-off demonstrations in Belfast ever since. So far, 70 people have been arrested in connection with the sporadic rioting and 47 people have been charged with criminal offences.

Terry Spence, chairman of the Police Federation for Northern Ireland, which represents the interests of police officers, said the firing of shots at police proved that paramilitaries had infiltrated the protests.
