Police in Northern Ireland have confirmed that a car found abandoned near Enniskillen in Co Fermanagh was carrying a viable device.
A security alert was raised when the vehicle was found on the Derrylin Road close to Thompsons Bridge yesterday morning.
A number of residents were removed from their homes during the alert, which has now ended.
Police said it was fortunate that no-one was killed.
PSNI district commander Pauline Shields said: "Although investigations are at an early stage it is our assessment at present that this vehicle was destined for Lisnaskea PSNI station."
The PSNI said the device consisted of approximately 60kg of homemade explosives contained in a beer keg.
The vehicle and bomb have been taken for further forensic examination.
Northern Ireland Secretary Theresa Villiers has condemned those behind the incident.
"Those responsible for it have neither mandate nor legitimacy; they are totally out of touch with what the vast majority of people in Northern Ireland want," she said.
"Acts like this only serve to strengthen our resolve against those terrorists who have nothing to offer Northern Ireland except mayhem and destruction."
