Thirty-six U.N. personnel have been killed in the Haiti earthquake, nearly 200 are still missing, and eight have been rescued from the rubble of collapsed buildings, U.N. officials said Thursday. Secretary General Ban Ki-moon told reporters that a U.N. security guard was pulled out from the collapsed U.N. headquarters building in Haiti's capital early on Thursday morning. He called the rescue of the Estonian guard “a small miracle” amid many deaths and the grim search for the missing. David Wimhurst, a spokesman for the U.N. peacekeeping mission in Haiti, said by videoconference from Port-au-Prince early Thursday afternoon that the dead include 19 U.N. peacekeepers, four international police officers, and 13 civilians. Wimhurst said about 160 U.N. national and international employees were unaccounted for, along with 18 police and 10 military personnel. The spokesman said eight U.N. staff have been rescued from rubble (seven from the headquarters building and one from a nearby U.N. office).
