Dissident Republicans are being linked with a gun attack on the PSNI station in Lisnaskea in Co.Fermanagh last night.
First reports suggested nobody was injured in the incident.
Tánaiste Eamon Gilmore condemned what he called a "deplorable act by terrorists".
Mr Gilmore said he extended solidarity to the PSNI officers and staff of the station who were targeted in a cold-bloded manner.
The Northern Ireland Justice MinisterDavid Ford condemned the attack, saying those behind it have "nothing positive to offer".
Local Assembly member Arlene Foster said the PSNI station had been attacked by automatic gunfire and described it as "reckless".
The Police Federation for Northern Ireland, which represents rank-and-file officers, tweeted: "Officers escape death when dissident republicans attack Lisnaskea station with gunfire. Cowardly and futile. Terrorism will never prevail."
