They are one of a number of 'Dissident' Republican groups which object to the Provisional IRA's cessation of hostilties. The 'Real' IRA have committed a number of attacks, most notably a bomb which exploded in a busy shopping street in Omagh, Northern Ireland in 1998. The Omagh bomb killed 29 people, mainly women and children. There were also a number of relatively minor attacks on mainland Britain, including a taxi-bomb attack on the BBC Television Centre in West London, and a rocket propelled grenade attack on the MI6 Headquarters, despite the continuing ceasefire and slow movement towards disarmament by the Provisional IRA.
