Document 3: Dissident Irish Republican campaign: Since the Provisional Irish Republican Army (IRA) called a ceasefire and ended its armed campaign in 1997, breakaway groups opposed to the ceasefire ("dissident Irish republicans") have continued a low-level armed campaign against the British security forces in Northern Ireland. The main paramilitaries involved are the Real IRA, Continuity IRA and Óglaigh na hÉireann. They have targeted the British Army and Police Service of Northern Ireland (PSNI, successor of the Royal Ulster Constabulary) in gun and bomb attacks, as well as with mortars and rockets. They have also carried out bombings that are meant to cause disruption. However, their campaign has not been as intensive as the Provisional IRA's.

One was killed by a non-specific republican group and another by the opposing Ulster Freedom Fighters (UFF). Of the others killed by the IRA, four were Protestant civilians. Three of them were killed in two separate car bomb explosions. The fourth Protestant civilian was shot because his firm was a contractor for the British Army and the Royal Ulster Constabulary (RUC).

Document 6: Provisional Irish Republican Army: The Provisional Irish Republican Army (Provisional IRA) was an Irish republican paramilitary organization that sought to remove Northern Ireland from the United Kingdom and to bring about an independent socialist republic encompassing all of Ireland. It was the biggest and most active republican paramilitary group during the Troubles. It saw itself as the successor to the original IRA and called itself simply the Irish Republican Army (IRA), or "Óglaigh na hÉireann" in Irish, and was widely referred to as such by others.
Document 7: Dissident republican: Dissident republicans, renegade republicans, anti-Agreement republicans or anti-ceasefire republicans (Irish: "poblachtach easaontach" ) are Irish republicans who do not support the current peace agreements in Northern Ireland. The agreements followed a 30-year conflict known as the Troubles, which claimed over 3,500 lives. During the conflict, republican paramilitary groups such as the Provisional Irish Republican Army waged a campaign to bring about a united Irish republic. Peace negotiations in the 1990s led to an IRA ceasefire in 1994 and to the Good Friday Agreement of 1998. Mainstream republicans, represented by Sinn Féin, supported the Agreement as a means of achieving Irish unity peacefully. 'Dissidents' saw this as an abandonment of republican ideals and acceptance of partition and British rule. They hold that the Northern Ireland Assembly and Police Service of Northern Ireland (PSNI) are illegitimate and see the PSNI as a "British paramilitary police force".
