Irish security forces are reportedly tracking 13 separate dissident republican cells after officers stopped what was described as a major bomb attack across the border. The development has raised fresh concerns about militant activity that many associate with the darkest years of the Troubles.

According to the report, the suspected attack involved a large explosive device discovered in the boot of a car earlier this week. The find appears to have prevented a potentially serious incident and has prompted renewed focus on cross-border security operations.

The report also says specialist garda units are monitoring hundreds of active members linked to dissident republican groups. That suggests authorities believe the threat is not limited to a single organisation, but spread across multiple cells capable of planning or supporting violent acts.

While only limited details are available, the case points to an ongoing security challenge in Ireland and along the border. The apparent scale of surveillance and the interception of a large car bomb indicate that police continue to treat dissident activity as a significant and active threat.
