TWO men have been charged in connection with the discovery of four deadly mortar bombs in Derry.
Meanwhile, gardai are investigating claims that the crude devices were constructed in the Republic and that the van used to transport them may have been bought in Dublin.
Two men, aged 35 and 37, were last night charged with the possession of explosives with intent to endanger life and conspiracy to cause an explosion.
One other man aged 31 was in custody and being quizzed in relation to the bombs find.
Police believe dissident republicans were within minutes of launching an attack with the mortars, describing them as "primed and ready to go".
A van, which was stopped by officers on the Letterkenny Road in Derry, had its roof cut back so the mortars could be fired.The New IRA is being blamed for the incident.
