Hundreds of people have protested at a controversial IRA parade in Northern Ireland.

The Tyrone Volunteers Day demonstration in Castlederg - a town close to the Irish border and repeatedly targeted by bombers -commemorated republicans who died during the violent conflict, including two men killed by their own device.

Unionist victims' campaigners waved fading black-and-white photos of loved ones killed during the troubles, and with memories still fresh some shouted angrily and two demonstrators temporarily broke through a security barrier amid emotional scenes in Co Tyrone.

Northern Ireland Secretary Theresa Villiers had urged organisers to call off the march, saying it was causing great hurt to victims of terrorism.

The parade followed Friday night's serious loyalist violence in Belfast city centre, when 56 Police Service of Northern Ireland officers were hurt by flying masonry.

The summer has seen heightened tensions around parading, flags and community relations which will be addressed by renewed political talks this autumn.

Unionists said the march was insensitive but Sinn Fein argued the town centre should be a shared space for nationalists and unionists and Stormont deputy First Minister Martin McGuinness said the intention was not to glorify terrorism.

Castlederg, close to the Irish border in the region's west, was one of the most bombed towns during the conflict.
