Irish Republican Army, also called the Provisional Irish Republican Army, is a republican paramilitary organisation seeking the establishment of a republic, the end of British rule in Northern Ireland, and the reunification of Ireland.

The group have been responsible for a number of bombings in the UK since the 1970s and have clashed with British armed forces and Loyalist paramilitaries in Northern Ireland for several decades.
