Four men and two women have appeared in court in Belfast charged in connection with a range of terror offences.
The six were arrested as part of a PSNI and M15 investigation into the dissident republican group, the New IRA.
So far 10 people have been detained as part of Operation Arbacia.
On Saturday, two men were remanded in custody after they were charged with a series of offences.
Meanwhile, a 49-year-old man, who was being questioned by the PSNI, has been charged with offences including membership of a proscribed organisation, directing terrorism and two counts of preparatory acts of terrorism.
The man, from the Dungannon area of Co Tyrone, is due to appear in court in Belfast tomorrow.
The PSNI is continuing to question one other suspect.
Three of the six people in court this morning have addresses in Co Tyrone, two come from Derry and the sixth is from Lurgan in Co Armagh.
During the hearing at Belfast's Laganside Court a solicitor for one of the accused claimed that an agent provocateur in the employ of MI5 or the PSNI had a role in the operation.
A PSNI officer gave evidence that the prosecution case centres on audio and video recordings of two meetings that took place.
A solicitor for another of the accused asked did an MI5 agent organise and finance the meetings, while a third solicitor said they are actively pursuing the issue of entrapment.
Joseph Patrick Barr, 32, of Cecilia's Walk, Derry; Amanda McCabe, 49, of Ailsbury Gardens, Lurgan, Co Armagh; Gary Hayden, 48, of Tyrconnell Street, Derry; Damien Mc Laughlin, 44, of Kilmascally Road, Ardboe, Co Tyrone; Sharon Jordan, 45, of Cappagh Road, Dungannon, Co Tyrone and Kevin Barry Murphy, 49, of Altowen Park, Coalisland, Co Tyrone, were charged with membership of a proscribed organisation, directing terrorism and two separate charges of preparatory acts of terrorism.
Mr McLaughlin also faced two separate charges of conspiracy to possess explosives, namely Semtex, with intent to endanger life and conspiracy to possess 100 rounds of ammunition with intent to endanger life.
No application for bail was made and District Judge Fiona Bagnall remanded all six accused in custody.
