Police have said a car bomb containing 130 pounds of explosives has been defused in Co Fermanagh.
British bomb experts carried out a controlled explosion on the suspect car which had been left outside a police station in the border village of Roslea.
A police spokesman described it as a crude but viable device, and said it could have endangered the lives of people if it had been activated.
A number of people had to leave their homes during the alert. The area around the police station remains sealed off.
The Chief Constable of the PSNI, Hugh Orde, has said the threat from dissident republicans remains significant following the car bomb attack. He said the dissidents had no local support and police would continue to clamp down on them.
