Extensive searches are continuing in Dublin today as part of a major crackdown on suspected members of the New IRA Alliance.
It follows the arrest of a 46 year old man on Wednesday following the discovery of a pipebomb in Cloughran.
A number of additional searches were carried out in the area yesterday and 10 kilogrammes of what's believed to be high-grade explosives were found.
Garda sources say the operation is still on-going and extended searches are continuing today.
