Updated on Sept. 20, 2026 in Terrorism

The Omagh Bomb inquiry resumed on 21 September 2026 to begin its third phase of hearings. This stage will last for four weeks and explore whether authorities could have prevented the 1998 attack that killed 29 people.
Why it matters
The inquiry seeks to determine if UK agencies possessed actionable intelligence that might have stopped the bombing. It also examines how cross-border cooperation could have influenced the outcome.
The investigation, now in its third phase, is currently examining intelligence sharing and warning calls related to the 15 August 1998 attack. Authorities are focusing on evidence involving the car used in the bombing, which was stolen two days prior in Carrickmacross.
