The number of United Nations staff killed in the Jan. 12 earthquake in Haiti has reached 84, while another 15 personnel remained unaccounted for, nearly three weeks after the disaster, UN officials said on Friday.

The toll, based on UN figures as of Friday morning, comprises 40 civilian staff who worked for the peacekeeping mission in Haiti, known as MINUSTAH, 24 military staff and 18 UN police officers. A World Food Program (WFP) staffer and a UN Volunteer (UNV) are also confirmed to have been killed.

The number of staff who have not been accounted for has fallen sharply in recent days as communications have improved and national staff members have been able to get in contact with the United Nations, said the officials.

The majority of the staff who remain unaccounted for worked for MINUSTAH, whose headquarters building in the capital, Port-au- Prince, was leveled by the 7.3-magnitude quake, which reportedly left at least 150,000 people dead.

Dozens of other UN staff members were hospitalized or injured as a result of the disaster, the officials said.
