The British Army has admitted that a Puma helicopter crossed the border into County Monaghan at the weekend.
The helicopter, with camouflage colouring flew up to two miles into County Monaghan and then over Clones town on its return to Co. Fermanagh.
Clones Councillor Pat Treanor hit out at the latest British Army incursion over the town and surrounding area on Sunday afternoon, whioch he said was “totally illegal and provocative”.
Cllr Treanor said : “It is particularly outrageous at the present time, when serious efforts are being made to bolster up the Peace Process.
“People are rightly suspicious and concerned by this incident. I have reported it to the local Gardai and have asked for an investigation.
A British Army spokesman accused Sinn Féin of making a “poor attempt to try and achieve political gain” from the incident.
