The Donagh to Rosslea road was closed for a search in April
The component parts of a very large bomb have been found near Rosslea in County Fermanagh, police have said.
The "very substantial explosive device", which included about 100lbs of fertiliser, was found in a field near the Donagh to Rosslea Road on Tuesday.
Six weeks ago dissident republicans warned of a device on the road.
PSNI Chief Inspector Alywin Barton said lives could have been lost: "Had these elements exploded, members of the public would have lost their lives."
He said the parts were also capable of causing serious injury and "widespread damage".
"This device was left very close to a house where children live and there was complete disregard for the fact that if these items had exploded then there could have been considerable damage, injury or death.

"This is a very, very strong example of how this small group of people are quite prepared to place very serious, very dangerous elements such as this close to property where people live."
Residents had to be evacuated from their homes on Wednesday while police searched the area.
It was the latest in a series of alerts in the county in the last year.
In recent weeks, police carried out a number of searches in response to the claim that a bomb had been abandoned on the road.
A police spokesperson said that there have been claims of other incidents which they had not been able to substantiate.

"The very vagueness and inaccuracy of these claims shows that we are right to be careful and treat them all with caution.
"In the meantime, we continue to urge the people of the area to be vigilant.
"They have been patient and supportive of police and we are determined to provide them with the community-based policing they ask for and deserve."
The police station in Lisnaskea is also to get extra security amid what police described as the "serious dissident threat" in parts of the county.
A planning application has been submitted to increase the steel fencing around the station by 2.5 metres.
