There were fresh calls today for heightened security at Shannon airport ahead of an anti-war demonstration on Saturday.
Concern was expressed after a group declared that it is planning to pull down the airport's perimeter fence.
The group - Grassroots Network Against War - posted a notice on its website calling on protesters to take part in a "mass non-violent civil disobedience".
Fine Gael's Mr Pat Breen said there was "grave concern" that the Co Clare airport would come under attack from peace activists.
"The Government must take pre-emptive action by increasing the number of army personnel in order to protect the airport," the Clare TD said.
Army patrols were drafted in to patrol Shannon after protesters broke through the perimeter fence and damaged a US military plane last month.
Protesters have been demanding that the Government withdraws permission from US planes to refuel at the airport on their way to the Gulf region.
Since the attacks on the US Navy plane three airlines have diverted their flights, refuelling at other airports instead.
Mr Richard Boyd Barrett, director of the Anti-War Movement, said the proposed breach of security was detracting from the real issues of the protest.
"I think it has been blown out of proportion," said Mr Boyd Barrett, whose group is organising Saturday's march.
