Private Seán Rooney is the 48th member of the Defence Forces to die while serving with the United Nations in southern Lebanon.
The Irish have been part of the special force called UNIFIL, which stands for United Nations Interim Force in Lebanon, on and off since May 1978.
Some 30,000 individual tours of duty have been carried out in the mission by Irish military personnel to southern Lebanon, which soldiers simply call The Leb.
