The IRA explodes bombs in the early morning at Paddington station and Victoria station in London.

The Provisional Irish Republican Army, officially known as the Irish Republican Army and informally known as the Provos, was an Irish republican paramilitary force that sought to end British rule in Northern Ireland, facilitate Irish reunification and bring about an independent republic encompassing all of Ireland. It was the most active republican paramilitary group during the Troubles. It argued that the all-island Irish Republic continued to exist, and it saw itself as that state's army, 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 unlawful organisation in the Republic of Ireland, both of whose authority it rejected.

On 18 February 1991 two Provisional Irish Republican Army (IRA) bombs exploded at London mainline stations, one at Victoria station and the other at Paddington station, killing one person and injuring 38 other people at Victoria station. It was the IRA's second major attack in London in February 1991 after the Downing Street mortar attack eleven days earlier which was an attempt to assassinate the British War cabinet and the British prime minister John Major. It was also the first IRA attack against a civilian target in England since the 1983 Harrods bombing, marking a strategic change in their bombing campaign in England.

Paddington, also known as London Paddington, is a London railway station and London Underground station complex, located on Praed Street in the Paddington area. The site has been the London terminus of services provided by the Great Western Railway and its successors since 1838. Much of the main line station dates from 1854 and was designed by Isambard Kingdom Brunel. As of the 2023–24 Office of Rail & Road Statistics, it is the second busiest station in the United Kingdom, after London Liverpool Street, with 66.9 million entries and exits.
