A bomb found and made safe in a car in Northern Ireland was destined for a police station, the Police Service of Northern Ireland (PSNI) said.
It was recovered in Co Fermanagh not far from the luxury Lough Erne golf resort where this June's G8 conference of world leaders is being held.
Dissident republicans are prime suspects.
PSNI district commander Pauline Shields said: "The people responsible for this have no regard for the lives of anyone in our community.
"It is fortunate that no-one was killed or seriously injured as a result of this reckless act."

The security alert on the Derrylin Road, Enniskillen, has ended.
Shields added: "Although investigations are at an early stage it is our assessment at present that this vehicle was destined for Lisnaskea PSNI station."
Following the report of a suspect vehicle in the area in the early hours of Friday a security operation was put in place which continued through the night until approximately 11am this morning.
Residents were evacuated from their homes and Army technical officers carried out a clearance operation on the suspicious car and a viable device was made safe.
Shields added: "Once again our community has been disrupted and the lives of residents put at risk by an element intent on causing loss of life and disruption.
"The people who carried out this act are not part of the society within which the majority of people of Northern Ireland wish to live. The subsequent complex operation has tied up resources that would otherwise be dealing with community issues."
Angela Merkel, Barack Obama and David Cameron are among those who will attend the meeting in three months
US president Barack Obama, German chancellor Angela Merkel and Russian prime minister Vladimir Putin are expected to attend the G8 meeting.
A massive security operation will be mounted and thousands of police officers from UK forces will be drafted in to help bolster PSNI numbers. They will help provide security and safety at a range of key venues and will be able to exercise the same powers of arrest, stop and search.
The finger of blame for the latest attempted attack on police will be pointed at dissident republicans, who have murdered two soldiers, two policemen and a prison guard in their campaign of violence.
A week ago officers discovered a mortar-type device aimed towards New Barnsley police station in north Belfast. Also, three officers escaped injury when an explosive device detonated within metres of them as they patrolled a coastal path on the outskirts of Belfast.
Earlier this month two men were arrested after police intercepted a van carrying four mortar bombs which were primed and ready to fire at a station in Londonderry.
