Republicans opposed to the Belfast Agreement tonight threatened a fresh campaign of violence.
The Real IRA said it would not stop until a 32-county Irish Republic had been achieved.
The Real IRA statement to mark the Easter rising warned: "British manipulation, coupled with treachery on the part of others, has led to and has upheld the partition of Ireland.
"As for Republicans, we will continue to attack the problem at its root and make no apology for undertaking this necessary task. We will continue our struggle until the 32 County Socialist Republic has been achieved."
Security forces earlier foiled a planned attack, which they believe was being mounted to mark this weekend's 1916 Easter rising commemorations.
A "barrack-buster" device was found at Altmore Forest, Galbally, Co Tyrone - just 10 miles from where the Real IRA carried out the 1998 Omagh attack.
