The body of one of two men missing in Lough Erne was discovered today in Co Fermanagh.
The body was found north of Devenish Island near Enniskillen during a search operation involving police and coastguard on both sides of the border.
The alarm was raised and the search began yesterday after the men's 16ft boat was discovered overturned in the lough.
Police confirmed the discovery of one of the missing men's body's shortly after 11:30am.
They urged members of the public who saw the green open fishing boat that the men were using after they left Enniskillen to help them trace the movements of the vessel.
An Irish Coastguard helicopter from neighbouring Co Sligo over the border has been deployed in the search.
Crew from Enniskillen inshore lifeboat and members of Lough Erne Coastguard Rescue Team have also been involved.
SDLP and Sinn Féin Assembly members in Fermanagh expressed their condolences to the family's of both men.
Tommy Gallagher of the SDLP said: "People are shocked that at least one life appears to have been lost on the Lough and that another man is still missing.
"I would like to extend our sympathies to the families of both individuals. No doubt the relatives of the man who is still missing are becoming very fearful for his safety.
"The fishing community will be rattled by what has happened."
Sinn Féin MLA Gerry McHugh said the lough was becoming more popular with people involved in water sports.
"Lough Erne has more and more people visiting it for angling, water skiing and cruises.
"An immense amount of visitors from Belfast come down every weekend almost at a drop of a hat to go there and Devenish is a very popular spot for tourists.
"I am obviously very sorry to learn about this tragedy. It is absolutely terrible."
