A Deputy Garda Commissioner has been chosen to lead a UN team that is to report on how Lebanese former prime minister Rafik Hariri was killed, the United Nations announced on Friday.
Mr Peter Fitzgerald is expected to leave for Beirut in the next few days to begin work, said UN spokesman, Mr Fred Eckhard.
Washington wants Security Council members to consider measures that could be taken against Mr Hariri's killers but it was unclear how many council members would agree.
On September 2nd, France and the United States engineered a council resolution demanding Syrian troops get out of Lebanon. That measure squeaked through 9-0 with six abstentions. A minimum of nine votes is needed for a resolution to pass.
Lebanese are divided over whether Syria, which has more than 14,000 troops and police in the country, had a role in the assassination. Syria has played a dominant role in Lebanon since the country's civil war in the 1970s. The United States recalled its ambassador in Damascus on Tuesday to express outrage over the assassination.
