The DUP has expressed grave concern about dissident republican activity following a bomb attack on Magilligan British army training camp in Co Derry.
The local MP, Mr Gregory Campbell, strongly condemned the bombing which has left a civilian Ministry of Defence worker critically ill. Security sources believe it was the work of the "Real IRA".
Mr Campbell said it was the latest in a series of attacks on security-force bases in his constituency. "There is a dangerous and very wrong perception that republican paramilitary organisations have gone away or else have very limited capabilities. That is not the case," he said.
"This is the latest in a long line of incidents in my constituency. There have been attacks on Ballykelly army base, Ebrington barracks, Claudy police station, and the Magilligan base itself was targeted 18 months ago.
"It is only good luck that no one has yet been killed. These people have not gone away and they have demonstrated that they remain dangerous. They are capable of carrying out deadly attacks."
Mr Campbell said he believed it was no coincidence that the Parachute Regiment, which shot dead 13 civilians on Bloody Sunday, was currently housed at the base. "Last week was the 30th anniversary of Bloody Sunday. Some people will draw the conclusion that it was a deliberate attack on the base where the Parachute Regiment are housed," he added.
The Northern Secretary, Dr John Reid, said the bombers were attempting to drag the North backwards. "The people who did this belong to a poisonous past," he said. He extended his sympathy to the victim and his family.
The attack was also condemned by the North's First Minister, Mr David Trimble. The Deputy First Minister, Mr Mark Durkan, called on the community not to allow those opposed to the Belfast Agreement to dictate the political agenda.
