Second ceasefire

On 9 February 1996, less than two years after the declaration of the ceasefire, the IRA revoked it with the Docklands bombing in the Canary Wharf area of London, killing two people, injuring 39 others, and causing £85 million in damage to the city's financial centre. Sinn Féin blamed the failure of the ceasefire on the British Government's refusal to begin all-party negotiations until the IRA decommissioned its weapons.

The attack was followed by several more, most notably the 1996 Manchester bombing, which destroyed a large area of the centre of the city on 15 June. It was the largest bomb attack in Britain since World War II. While the attack avoided any fatalities due to a telephone warning and the rapid response of the emergency services, over 200 people were injured in the attack, many of them outside the established cordon. The damage caused by the blast was estimated at £411 million. Lance bombardier Stephen Restorick, the last British soldier killed during the Troubles, was shot dead at a checkpoint on the Green Rd near Bessbrook on 12 February 1997 by the IRA's South Armagh sniper.

The IRA reinstated their ceasefire in July 1997, as negotiations for the document that became known as the Good Friday Agreement began without Sinn Féin. In September of the same year, Sinn Féin signed the Mitchell Principles and were admitted to the talks. The UVF was the first paramilitary grouping to split as a result of their ceasefire, spawning the Loyalist Volunteer Force (LVF) in 1996. In December 1997, the INLA assassinated LVF leader Billy Wright, leading to a series of revenge killings by loyalist groups. A group split from the Provisional IRA and formed the Real IRA (RIRA).

In August 1998, a Real IRA bomb in Omagh killed 29 civilians, the most by a single bomb during the Troubles. This bombing discredited " dissident republicans " and their campaigns in the eyes of many who had previously supported the Provisionals' campaign. They became small groups with little influence, but still capable of violence.

The INLA also declared a ceasefire after the Good Friday Agreement. Since then, most paramilitary violence has been directed at their "own" communities and at other factions within their organisations. The UDA, for example, has feuded with their fellow loyalists the UVF on two occasions since 2000. There have been internal struggles for power between "brigade commanders" and involvement in organised crime.
