Huge crowds in Dublin at a requiem mass for the victims of the Dublin bombings held in the Pro Cathedral.

Twenty six people were killed by a series of car bombs planted by loyalists on 17 May in Parnell Street, Talbot Street and South Leinster Street in Dublin. Later that day, a bomb in Monaghan Town killed a further seven people. Almost 300 more were injured in what was to be one of the worst terrorist attacks of the troubles.

At a requiem mass the chief celebrant was Dr Desmond Ryan, Archbishop of Dublin. The mass at the Pro Cathedral was attended by an Taoiseach Liam Cosgrave, President Erskine Childers and his wife Rita. Others present include Éamon de Valera, Jack Lynch and his wife Máirín, Michael O'Leary, Conor Cruise O'Brien, Tom O'Donnell, Paddy Donegan and Frank Aiken.

The coffins of six of the victims were placed before the altar: Mary McKenna, John Dargle and the entire O'Brien family. Parents Anne and John O'Brien had been killed along with their babies Jacqueline and Anne Marie in Parnell Street. Their burial at Glasnevin Cemetery by Fr Patrick McCabe is also shown.
