An estimated 600 people took part in the annual Bloody Sunday commemoration march in Derry this afternoon.
They retraced the original route of the civil rights march from the Creggan shops as far as the city centre in memory of the 14 civilians killed by British army paratroopers on 30 January 1972.
Former MP Bernadette McAliskey, who was one of the organisers of the march on 30 January 1972, said the families of the 14 victims killed by British paratroopers are still waiting for prosecutions against the soldiers involved.
The families learnt a few weeks ago of the death of Soldier N, who was among 18 soldiers being considered for prosecution by the Public Prosecution Service in connection with the attack.
"In regard to the prosecution of those soldiers, we are not moving forward more than an inch at the time. Soldier 'N' has died. Family members are dying," said Ms McAliskey.
The march is an annual event. However, it has been a week of tension in Derry since last Saturday night's car bomb which exploded outside the city's courthouse on Bishop Street.
Last night the PSNI staged a reconstruction of that attack at the same location in the city.
The police said in a statement afterwards that they are progressing in their investigation. They handed out leaflets asking for the public for any information they might have on the attack.
