An IRA bomb devastates the Bishopsgate area of London.
The Bishopsgate bombing occurred on 24 April 1993, when the Provisional Irish Republican Army (IRA) detonated a powerful truck bomb on Bishopsgate, a major thoroughfare in London's financial district, the City of London. Telephoned warnings were sent about an hour beforehand, but a news photographer was killed in the blast and 44 people were injured, with fatalities minimised due to it occurring on a Saturday. The blast destroyed the nearby St Ethelburga's church and wrecked Liverpool Street station and the NatWest Tower.As a result of the bombing, which happened just over a year after the bombing of the nearby Baltic Exchange, a "ring of steel" was implemented to protect the City, and many firms introduced disaster recovery plans in case of further attacks or similar disasters. £350 million was spent on repairing damage. In 1994 detectives believed they knew the identities of the IRA bombers, but lacked sufficient evidence to arrest them.
The Irish Republican Army (IRA; Irish: Óglaigh na hÉireann), also known as the Provisional Irish Republican Army, and informally as the Provos, was an Irish republican paramilitary organisation that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent, socialist republic encompassing all of Ireland. It was the most active republican paramilitary group during the Troubles. It saw itself as the army of the all-island Irish Republic and as the sole legitimate successor to the original IRA from the Irish War of Independence. It was designated a terrorist organisation in the United Kingdom and an illegal organisation in the Republic of Ireland, both of whose authority it rejected.
The Provisional IRA emerged in December 1969, due to a split within the previous incarnation of the IRA and the broader Irish republican movement. It was initially the minority faction in the split compared to the Official IRA, but became the dominant faction by 1972. The Troubles had begun shortly before when a largely Catholic, nonviolent civil rights campaign was met with violence from both Ulster loyalists and the Royal Ulster Constabulary (RUC), culminating in the August 1969 riots and deployment of British soldiers. The IRA initially focused on defence of Catholic areas, but it began an offensive campaign in 1970 that was aided by weapons supplied by Irish American sympathisers and Libyan leader Muammar Gaddafi. It used guerrilla tactics against the British Army and RUC in both rural and urban areas, and carried out a bombing campaign in Northern Ireland and England against military, political, and economic targets, and British military targets in Europe.
The Provisional IRA declared a final ceasefire in July 1997, after which its political wing Sinn Féin was admitted into multi-party peace talks on the future of Northern Ireland. These resulted in the 1998 Good Friday Agreement, and in 2005 the IRA formally ended its armed campaign and decommissioned its weapons under the supervision of the Independent International Commission on Decommissioning. Several splinter groups have been formed as a result of splits within the IRA, including the Continuity IRA and the Real IRA, both of which are still active in the dissident Irish republican campaign. The IRA's armed campaign, primarily in Northern Ireland but also in England and mainland Europe, killed over 1,700 people, including roughly 1,000 members of the British security forces, and 500–644 civilians. In addition 275–300 members of the IRA were killed during the conflict.
