The Continuity IRA last night issued a warning against council employees providing services to security force bases.
The warning came as the dissident republican group admitted responsibility for Monday night's bomb attack on Enniskillen town hall.
The group also admitted carrying
out an attack on Stewartstown police station at the weekend.
Calling on all district councils to stop providing public services, such as
bin collections, to police and army bases, the CIRA statement warned that attacks on security force bases would continue.
Referring to a vow by the Republic's minister for justice and law reform, Michael McDowell, who promised that Bertie Ahern's government would continue to crack down on dissident republicans, the CIRA statement read: "Threats from Free State ministers such as Michael McDowell will not deter us in our objective, which remains the removal of the British."
The larger of the two dissident republican groups, the Real IRA, was established in 1997 by a former Provisional IRA quarter-master general.
While the Continuity IRA had been in existence for a number of years previous to that, the Real IRA's bomb-making capabilities are seen to pose the greater security threat.
In the last three years the Real IRA has carried out a number of 'spectaculars' in London, with bomb attacks on BBC headquarters, Hammersmith Bridge and MI6 headquarters.
Since then it has attempted to fire home-made mortars at army bases
in Armagh, Tyrone and Derry on a
number of occasions.
Dissident attempts to import arms from eastern Europe were thwarted in July 2000 when a major arms shipment from Croatia was intercepted.
The shipment included heavy machine guns, rocket-propelled grenades, plastic explosives and anti-tank weapons. Weapons similar to those found in Croatia were recovered in Co Meath in October 1999.
In August 1998 the Real IRA received its biggest setback with the public outcry it provoked by bombing Omagh town centre, killing 29 people including a woman pregnant with twins.
That attack caused such outrage that the group was forced to call a ceasefire.
But uncertainty over the peace process and anger over the speed of reforms following the Good Friday Agreement appear to have encouraged both dissident groups to increase their levels of attacks in the last 18 months.
In August last year 51-year-old civilian army base worker David Caldwell was killed when a booby-trap bomb explod-ed at a Territorial Army base in Derry.
A bomb attack at Magilligan army base in February last year left another civilian worker critically injured.
Republican sources insist that a key plank of the dissidents' strategy is to mount high-profile attacks at times of key political negotiations. The strategy is based on the belief that the attacks not only put pressure on the British government but also effectively bar Sinn Féin from being able to broker any breakthrough deal with unionists.
Monday's attack in Enniskillen is seen in the context of the arrival of British prime minister Tony Blair and Taoiseach Bertie Ahern in Northern Ireland today for talks aimed at re-establishing the Stormont institutions.
In the aftermath of Monday night's bombing a CIRA spokesman warned: "The British had better be prepared. There will always be people prepared to take up arms against their rule here."
