The Provisional Irish Republican Army declares the end to its 18-month ceasefire and explodes a large bomb in London's Canary Wharf, killing two people.

The London Docklands bombing (also known as the South Quay bombing or erroneously referred to as the Canary Wharf bombing) occurred on 9 February 1996, when the Provisional Irish Republican Army (IRA) detonated a powerful truck bomb in South Quay (which is outside Canary Wharf). The blast killed two people and devastated a wide area, causing an estimated £150 million worth of damage. The IRA had sent warnings 90 minutes beforehand, but the area was not fully evacuated. As well as the two people who were killed, more than 100 were injured, some permanently.

The attack marked an end to the IRA's seventeen-month ceasefire, and came just over an hour after its declaration to Irish broadcaster RT. The IRA agreed to the ceasefire in August 1994 on the understanding that Sinn Fin would be allowed to take part in peace negotiations, but resumed its campaign with the Docklands bombing when the British government demanded a full IRA disarmament as a precondition for talks. After the bombing, the British government dropped its demand. A few months later, the IRA detonated another, more powerful truck bomb in Manchester.

IRA member James McArdle was convicted of the bombing in 1998. He had been a member of an IRA sniper team in South Armagh. He was released two years later, under the terms of the Good Friday Agreement.

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.
