Five men have been arrested in Co Louth following the discovery of an improvised explosive device.

The device was discovered when armed officers from the Emergency Response Unit stopped a car in Kilcurry, a village 8km north of Dundalk

A beer keg was found in the back with a number of components used in improvised explosive devices.

Gardaí believe the five, who are being held in Garda stations in Dundalk and Drogheda, are linked to dissident republican group Óglaigh na hÉireann.

The operation was part of an investigation by Crime and Security and the Special Detective Unit into the activities of dissident republicans

The scene was preserved and the Army Bomb Disposal Team was called in to examine the device and make the area safe. 

Gardaí suspect it was being transported to Northern Ireland.

The men are aged in their mid-50s to early 70s and are known to gardaí.
