Bloody Friday is the name given to the bombings by the Provisional Irish Republican Army (IRA) in Belfast, Northern Ireland on 21 July 1972, during the Troubles. At least twenty bombs exploded in the space of eighty minutes, most within a half-hour period. Most of them were car bombs and most targeted infrastructure, especially the transport network. Nine people were killed: five civilians, two British soldiers, a Royal Ulster Constabulary (RUC) reservist, and an Ulster Defence Association (UDA) member, while 130 were injured.Northern Ireland Office news-sheet. Conflict Archive on the Internet (CAIN) The IRA said it sent telephoned warnings at least thirty minutes before each explosion and said that the security forces wilfully ignored some of the warnings for their own ends. The security forces said that was not the case and said they were overstretched by the sheer number of bombs and bomb warnings, some of which were hoaxes.

The bombings were partly a response to the breakdown of talks between the IRA and the British government. Since the beginning of its campaign in 1970, the IRA had carried out a bombing campaign against civilian, economic, military and political targets in Northern Ireland and less often elsewhere. It carried out 1,300 bombings in 1972. However, Bloody Friday was a major setback for the IRA as there was a backlash against the organisation. Immediately after the bombings, the security forces carried out raids on the homes of republicans. Ten days later, the British Army launched Operation Motorman, in which it re-took the no-go areas controlled by Republicans. Loyalist paramilitaries also reacted to the bombings by carrying out "revenge" attacks on Catholic civilians.

On the thirtieth anniversary of the bombings, the IRA formally apologised to the families of all the civilians it had killed and injured.Irish Republican Army statement, 16 July 2002. Conflict Archive on the Internet (CAIN)"Q&A: The IRA's apology". BBC News, 16 July 2002.

Background In late June and early July 1972, a British government delegation led by Secretary of State for Northern Ireland William Whitelaw held secret talks with the Provisional IRA leadership. As part of the talks, the IRA agreed to a temporary ceasefire beginning on 26 June. The IRA leaders sought a peace settlement that included a British withdrawal from Northern Ireland by 1975 and the release of republican prisoners. However, the British refused and the talks broke down. The ceasefire came to an end on 9 July.

"Bloody Friday" was the IRA's response to the breakdown of the talks. According to the IRA's Chief of Staff, Seán Mac Stíofáin, the main goal of the bombing operation was to wreak financial harm."Bloody Friday: What Happened". BBC News, 16 July 2002. Retrieved 7 March 2011. It was a "message to the British government that the IRA could and would make a commercial desert of the city unless its demands were met".Maloney, Ed. Voices From the Grave: Two Men's War in Ireland. US: Faber & Faber, 2010. p.104 The attack was carried out by the IRA's Belfast Brigade and the main organiser was Brendan Hughes, the brigade's Officer Commanding.

The bombings The bombings happened during an 80-minute period on the afternoon of Friday 21 July. At least 24 bombs were planted; at least 20 exploded and the rest failed to detonate or were defused. At the height of the bombing, the middle of Belfast "resembled a city under artillery fire; clouds of suffocating smoke enveloped buildings as one explosion followed another, almost drowning out the hysterical screams of panicked shoppers".Moloney, A Secret History of the IRA, p.116 According to The Guardian: "for much of the afternoon, Belfast was reduced to near total chaos and panic. Thousands streamed out of the stricken city […] and huge traffic jams built up. All bus services were cancelled, and on some roads, hitchhikers frantically trying to get away lined the pavements".Hoggart, Simon. "11 die in Belfast hour of terror". The Guardian, 22 July 1972.

Nine people were killed and a further 130 injured, some of them horrifically mutilated. Of those injured, 77 were women and children.Moloney, A Secret History of the IRA, p.302 All of the deaths were caused by two of the bombs: at Oxford Street bus depot, and at Cavehill Road. The Oxford Street bomb killed two British soldiers and four Ulsterbus employees. One of these employees was a Royal Ulster Constabulary (RUC) reservist; one was an Ulster loyalist paramilitary; and the other two were civilians. The Cavehill Road bomb killed three civilians.
