The INLA was founded by former members of the Official Irish Republican Army who opposed that group 's ceasefire . It was initially known as the " People 's Liberation Army " or " People 's Republican Army " . The INLA waged a paramilitary campaign against the British Army and Royal Ulster Constabulary ( RUC ) in Northern Ireland . It was also active to a lesser extent in the Republic of Ireland and Great Britain . High-profile attacks carried out by the INLA include the Droppin Well bombing , the 1994 Shankill Road killings and the assassinations of Airey Neave in 1979 and Billy Wright in 1997 . However , it was smaller and less active than the main republican paramilitary group , the Provisional IRA . It was also weakened by feuds and internal tensions . Members of the group used the covernames People 's Liberation Army ( PLA ) , People 's Republican Army ( PRA ) and Catholic Reaction Force ( CRF ) for attacks its volunteers carried out but the INLA did n't want to claim responsibility for . The INLA became a proscribed group in the United Kingdom on the 3 July 1979 under the 1974 Prevention of Terrorism Act
