Two men remain in Garda custody at Killarney garda station following the discovery of an arms dump in South Kerry.
The Special Detective Unit, local gardaí and Army troops raided a location near Sneem yesterday.
They found guns, ammunition and bomb parts, and arrested two men - one in his fifties, the other in his twenties.
Kerry Fine Gael TD Brendan Griffin says it's a reminder that Ireland's history of armed violence hasn't gone away.
