Intercepted Explosives Spark High-Level “Tout” Inquiry
The discovery of a vehicle-borne booby-trap device by Gardaí has thrown the New IRA into internal turmoil, triggering widespread suspicions of high-level informers operating within its Derry apparatus.
An internal dissident inquiry—reportedly directed by a senior figure from East Tyrone—was initiated after Irish security forces stopped a vehicle carrying Semtex explosives along the N2 near Carrickmacross, Co Monaghan. The explosive device was allegedly intended for an attack on a Police Service of Northern Ireland (PSNI) officer based at Strand Road station in Derry.
Scrutiny has centered on two prominent Derry figures: one who oversaw the planning of the proposed strike, and another who served as the primary contact with Dublin-based dissidents.
Logistical Failures: Dissidents Blame Security Blunders
Insiders within the movement have sharply criticized the logistics of the intercepted plot, describing the plan to move military-grade explosives across a three-hour transit route from Dublin as a severe breakdown in basic security.
“Every extra minute that device spent on the highway heightened the likelihood of detection. If this operation were managed professionally, the bomb would have been staged near the border in Donegal rather than driven across the country,” a source noted.
Questions are also being raised over why authorities interdicted the vehicle in Monaghan rather than allowing it to cross into Northern Ireland under tactical surveillance to identify the intended recipients.
Court Proceedings and Terror Charges
Two individuals currently face charges in connection with the Monaghan seizure:
- Isobella Perrie Sullivan (25): A law student intercepted while driving the car containing Semtex and a detonator. Her defense team contended she was manipulated into transporting the cargo without knowledge of its contents. She has since been released on bail.
- Simon O’Donovan (44): A museum worker subsequently charged over involvement in the explosives transport. He remains in custody on remand.
Internal Strife and Declining Support in Derry
The thwarted attack underscores the ongoing operational decay within the New IRA’s Derry network. While Derry remains the group’s largest concentration with roughly 45 active members out of an estimated 250 nationwide, security analysts note its capability has steadily deteriorated following intense law enforcement pressure after the 2019 murder of journalist Lyra McKee.
The fallout is also impacting the group’s political associate, Saoradh:
- Diminishing Engagement: Turnout at headquarters (Junior McDaid House) and organizational meetings has dropped significantly, with routine absences among the ranks.
- Prisoner Pushback: Strains with incarcerated dissidents led republican prisoners to withhold permission for an official statement to be read on their behalf during a recent event in Dungiven.
- Frictional Leadership: Figures such as Barry Millar have drawn internal criticism regarding public representation and declining attendance at regional gatherings.
Following earlier unsuccessful explosive attempts outside PSNI stations in Lurgan and Dunmurry, security officials had correctly identified Derry as the next probable target zone. The subsequent interception leaves the New IRA facing heightened surveillance, diminished internal trust, and growing factional divide.
