Northern Ireland security forces defused a car bomb on Saturday near where world leaders will meet for the G8 summit in June, officials said.
Army bomb disposal experts cleared the "viable device" near Enniskillen, County Fermanagh, which was believed to be destined for a local police station, said police.
The site where the bomb was found is about 12 miles (19 kilometres) from the five-star Lough Erne hotel and golf resort where leaders of the Group of Eight richest nations meet on June 17 and 18.
Britain holds the rotating chairmanship of the G8 and the decision to hold the summit in Northern Ireland was seen as a major boost for the province after decades of sectarian violence.
"It is fortunate that no-one was killed or seriously injured as a result of this reckless act," said Pauline Shields, the district commander of the Police Service of Northern Ireland.
"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."
Northern Ireland Secretary Theresa Villiers, the London-based minister responsible for the province, said such acts "only serve to strengthen our resolve against those terrorists."
There was no immediate claim of responsibility but recent sporadic attacks in Northern Ireland have been blamed on dissident republicans who want it to be part of the Republic of Ireland.
A 1998 peace agreement brought an end to three decades of sectarian violence between Protestants and Catholics known as the Troubles, during which around 3,500 people died.
