It has been confirmed that the body of UN aid worker Andrew Grene, a US citizen originally from Co Cavan, has been found in Haiti.
Grene was working at the United Nations building in the capital Port Au-Prince which collapsed in last week's quake.
"I have learned with great regret from the UN of the death of Mr Andrew Grene in such tragic circumstances in Haiti," said Minister for Foreign Affairs Micheál Martin.
"I want to extend my own personal condolences and that of the Irish Government to his family in the United States and Ireland on this very sad occasion.
"He was a true humanitarian, working for the good of the people of Haiti. His post in the UN in Haiti was as assistant to the secretary general's special representative, Mr Hedi Annabi, who also tragically lost his life when the earthquake struck.
"Andrew is part of a long and honourable Irish tradition of public service with the United Nations. His family, and indeed Ireland, can be very proud of his work. He was also a citizen of the United States and I know that that country also takes pride in his achievements.
"My thoughts are with Andrew’s wife and children and all his family and friends at this difficult time.
"Ar dheis Dé go raibh a anam uasal."
