Visits to Maghaberry Prison in Co Antrim were halted again today following the discovery of a bomb detonator and bullets.
The find is believed to be linked to a bid for segregation by loyalists and republicans.

Loyalists and republicans are demanding to be kept apart, and security sources believe the detonator and bullets, one of which exploded in a toaster, were smuggled in to try and heighten the pressure on the prison authorities.
