The deadliest attack in the Republic's history left no one charged
In short: On May 17, 1974, three car bombs detonated in Dublin during the evening rush hour, followed by a fourth in Monaghan. These coordinated strikes killed 34 civilians and remain a haunting chapter of the Troubles—an act of international terrorism where no one has ever been prosecuted.
The bombings were carried out by the Ulster Volunteer Force (UVF), a loyalist paramilitary group from Northern Ireland. The attacks occurred during the Ulster Workers' Council strike, a general strike aimed at collapsing the Sunningdale Agreement, which sought to share political power with Irish nationalists. The Republic of Ireland had supported this agreement, making the bombings a direct strike against the state's involvement in Northern Irish governance.
The technical precision of the explosives was noted by military experts; 100% of each bomb exploded upon detonation. In Dublin, three hijacked cars—a Hillman Avenger, a Ford Escort, and an Austin 1800—were detonated at Parnell Street, Talbot Street, and South Leinster Street. The Monaghan blast involved a stolen 1966 Hillman Minx weighing 68 kilograms (150 lb). While the Dublin bombs targeted busy thoroughfares during a bus strike to maximize casualties, the Monaghan bombing may have served as a 'supporting attack' or diversion to facilitate the bombers' escape back to Northern Ireland.
Despite the scale of the tragedy—which killed many young women and even an unborn child—no one has ever been charged. A 2003 government inquiry by Mr. Justice Henry Barron criticized the Garda Síochána for stopping their investigation prematurely and highlighted a lack of interest from the Fine Gael/Labour government at the time. The report suggested that British military personnel, including members of the 'Glenanne gang,' likely assisted the UVF. However, the investigation remains incomplete as the British government has refused to release key documents requested by victims' families.
