Police teams, using a helicopter, were this week continuing a search of the Wattlebridge Road area following reports that a coffee jar bomb had been thrown at a three-vehicle PSNI convoy in the area on Monday night of last week.
On Monday afternoon of this week, a male caller, who claimed to speak on behalf of the Real IRA Republican Army, telephoned the 'Herald' office and claimed responsibility for a coffee jar attack on the Wattlebridge Road on the Cavan to Newtownbutler Road.
"Volunteers carried out their attack on Monday night (23rd June) on a passing three-car Police patrol".
The caller referred to conflicting reports doing the rounds and that is organisation wished to confirm that an attack did take place.
He then repeated the name of the organisation, using a code word which he said was recognisable.
A PSNI spokesman said Police were aware of the claim that it was a terrorist coffee jar attack. He went on:
"While we have no information nor knowledge of this incident, we feel it is prudent to carry out a search operation, and we advise the public of the need for care".
Commenting on the attack on the PSNI, Arlene Foster, an Assembly member for the area, has reiterated her call for extra resources to deal with the dissident terrorists in Fermanagh.
"I recently spoke to Assistant Chief Constable Gillespie," she said, "and in that meeting we discussed the need for extra resources in this area.
"It is imperative the community on the ground feel confident and secure in their homes and as they go about their daily business.
"Extra police on the ground in this area will ensure this happens," she urged.
"Those who are trying to terrorise people in this area should be given the message from all political parties that this activity is not acceptable, and that their efforts to intimidate people in this area is not going to work.
These dissidents have no public representation. They are not wanted by those they claim to represent, and it is time that they got that message."
