Gardaí intercepted a woman driving a suspected car bomb on the N2 near Carrickmacross; authorities described the device as the most sophisticated explosive seen since the Troubles. The New IRA, estimated to have 20–30 active members and roughly 200 supporters, is blamed for recent attacks including car bombs outside police stations in Lurgan and Dunmurry. Long-term MI5 infiltration and Operation Arbacia have weakened the group, but recent violence and threats against officers show it remains dangerous and may be trying to regain credibility or influence court cases.
Suspected New IRA Car Bomb Intercepted Near Carrickmacross — Group Remains Weakened but Dangerous

On the N2 just south of Carrickmacross, officers from the Gardaí Special Detective Unit carried out a planned interception after identifying a woman driving what investigators say was a sophisticated car bomb bound for Northern Ireland.
The Incident
Irish police described the device as the most advanced explosive they have encountered since the worst years of the Troubles. The vehicle was stopped before it could cross the border, averting what authorities say could have been a deadly attack.
Who Are The Dissidents?
The New IRA is the largest dissident republican group currently active in Northern Ireland. Security services estimate it comprises roughly 20–30 active members and perhaps 200 sympathisers who might assist operations. Despite this, the group has little public support and is a fraction of the size and capability of the Provisional IRA during the Troubles.
Recent Alleged Attacks
Police suspect the New IRA of involvement in car bombs placed outside police stations in Lurgan (March) and Dunmurry (April). If proven, investigators trace the plot’s origins to earlier network activity dismantled in 2020.

Operation Arbacia And Infiltration
In 2020, Operation Arbacia resulted in the arrest of ten people, some described as members of the New IRA's so-called "army council", following an extensive undercover surveillance campaign. Reports say an MI5 agent, operating over two decades, infiltrated the network and made covert recordings. Those arrests dealt a serious blow to the group's organisation and credibility.
Violence And Reprisal
The group has continued violent activity, including the February 2023 shooting of Detective Chief Inspector John Caldwell outside a leisure centre in Omagh. Mr Caldwell, who had been coaching a youth football session and had worked on investigations including the Lyra McKee murder, survived the attack. That shooting prompted a major counter-terror operation and further arrests.
"A Wounded But Still Lethal Threat"
Security services and police on both sides of the border, backed by MI5 activity, have repeatedly disrupted dissident cells. In April, MI5 reportedly sent targeted video messages to suspected members urging them to lay down arms. Nonetheless, the group has issued threats to "execute" police officers and continues to pose a lethal risk when it attempts attacks.
What Motivates The Recent Surge?
Analysts suggest the recent uptick in incidents could be an effort to restore credibility, rally supporters or influence ongoing trials linked to Operation Arbacia. The timing — after a period in which Sinn Féin has taken prominent political positions in Northern Ireland — may also be intended to exploit political sensitivities.
In short, the New IRA remains a diminished and pressured organisation, but the intercepted car bomb underscores that even a weakened group can still mount dangerous attacks.
