Three Provisional Irish Republican Army volunteers are shot dead by the SAS in Gibraltar in Operation Flavius.

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.

The Special Air Service (SAS) is a special forces unit of the British Army. It was founded as a regiment in 1941 by David Stirling, and in 1950 it was reconstituted as a corps. The unit specialises in a number of roles including counter-terrorism, hostage rescue, direct action and special reconnaissance. Much of the information about the SAS is highly classified, and the unit is not commented on by either the British government or the Ministry of Defence due to the secrecy and sensitivity of its operations.

Gibraltar is a British Overseas Territory and city located at the southern tip of the Iberian Peninsula, on the Bay of Gibraltar, near the exit of the Mediterranean Sea into the Atlantic Ocean. It has an area of 6.8 km² (2.6 sq mi) and is bordered to the north by Spain. The landscape is dominated by the Rock of Gibraltar, at the foot of which is a densely populated town area. Gibraltar is home to around 34,000 people, primarily Gibraltarians.

Operation Flavius was a military operation in which three members of the Provisional Irish Republican Army (IRA) were shot dead by the British Special Air Service (SAS) in Gibraltar on 6 March 1988. The trio were believed to be planning a car bomb attack on British military personnel in Gibraltar. They were shot dead while leaving the territory, having parked a car. All three were found to be unarmed, and no bomb was discovered in the car, leading to accusations that the British government had conspired to murder them. An inquest in Gibraltar ruled that the authorities had acted lawfully but the European Court of Human Rights held that, although there had been no conspiracy, the planning and control of the operation was so flawed as to make the use of lethal force almost inevitable. The deaths were the first in a chain of violent events in a fourteen-day period. On 16 March, the funeral of the three IRA members was attacked, leaving three mourners dead. At the funeral of one, two British soldiers were murdered after driving into the procession in error.
