In the North, seven men have been charged with terrorism offences, by police investigating violent dissident republican activity.
They were among 12 men held in Newry last Monday during a probe into the Continuity IRA.
It's believed some of those are from the Republic.
The 7 accused - aged between 30 and 75 - are due in court this morning.
Five others were released pending report to the Public Prosecution Service.
Gardai are continuing to question two men over dissident republican activity in Dublin.
The men - both aged in their 50s - were arrested on Saturday, after five guns were seized during a garda raid on a house in East Wall.
They're being held at Mountjoy and Coolock Garda Stations
Separate searches were carried out yesterday in Ballymun, East Wall and Cloughran, where semi automatic pistols, a sawn-off shotgun and an AK 47 assault rifle were all seized.
Gardaí also discovered bomb making material at one of the locations.
