Gardaí have seized a number of firearms, explosives and ammunition as part of an ongoing operation against the activities of criminal gangs in the Limerick area.

A number of sub-machine guns, a quantity of hand grenades and pipe bombs were among items discovered during a search of a small cottage, located close to the village of Ahane in Co Limerick.

A number of follow-up searches were also being carried out and the Army bomb unit assisted gardaí in assessing the viability of the devices found.

The find comes as gardaí continue to target the activities of a number of different factions involved in serious crime, and other criminal activity in Limerick.
