The New IRA has indicated it will continue its armed campaign despite speculation that it may call a ceasefire after a year of significant setbacks which put its alleged leadership behind bars.
In a hardline Easter statement, the organisation paid tribute to its membership and said efforts to defeat republicanism had failed.
"The IRA will continue to attack the problem at its root, and make no apology for undertaking this necessary task," it said.
"The IRA will continue our struggle until a 32-county socialist republic has been achieved."
Ten people are currently in custody accused of a total of 39 offences, including directing terrorism and trying to obtain Semtex, as part of the MI5-led Operation Arbacia last summer.
More arrests are expected on the basis of secret recordings of New IRA meetings made by British agent Dennis McFadden who became involved in Sinn Fein over 20 years ago before joining the dissidents.
The New IRA has been largely inactive since Operation Arbacia, but it gave no indication in its Easter statement that it was preparing to call a ceasefire.
The paramilitary group said that despite ongoing Brexit turmoil and "a rise in militant loyalism", Britain remained determined "to quash republicanism".
The New IRA added: "They have failed and their efforts have been in vain. While the liberation of Ireland has not yet been achieved, British manipulation coupled with the treachery of former republicans has upheld the partition of Ireland.
"For the solution, the army must look in radical terms to attacking the cause of Ireland's problems.
"Almost 100 years since the partition of Ireland, it's clear it has failed and those who attempt to uphold it will fail."
Meanwhile, members of Saoradh, the New IRA's alleged political wing, held a wreath-laying ceremony in Derry City Cemetery yesterday with around 30 people present.
A planned march for the event to mark the 105th anniversary of the Easter Rising was cancelled.
The ceremony passed off without police intervention. DUP MLA Gary Middleton said he would be raising the issue with the PSNI.
Saoradh national executive member Stephen Murney said: "Saoradh are reminded that men and women were incarcerated in British and 26 county jails for standing by the Republic proclaimed in 1916."
Mr Murney claimed Saoradh "grew more confident daily in our political analysis and position".
He said: "The British and 26 county establishments must fear our message and our analysis as we continue to bear the wrath of MI5-led harassment across the country.
"Our social media pages face regular censorship, yet we are getting our message out there and it is resonating with people."
Mr Murney added: "We hope to pass the unrepentant revolutionary republican flame onto the next generation.
"We remember that in 1916, it was so-called dissidents and radicals within the broader nationalist movement who led the charge and pushed the revolutionary agenda forward to rise and strike a blow for liberty.
"We are proud to inherit the title dissident in the Irish context.
"The Good Friday Agreement was not the end of Irish history.
"There has been and always will be dissenting voices until the socialist republic that so many gave so much for is achieved."
