The deaths of 16 UN workers in Tuesday's massive earthquake have already been confirmed, and "It's clear a high number" of those still missing "might be dead," a top UN official told the Washington Post. The missing staffers are trapped under the rubble of their collapsed headquarters as well as other UN facilities in Haiti. Secretary-General Ban Ki-Moon said Tuesday's earthquake would likely mark the worst day in UN history, with a death toll surpassing the 44 peacekeepers killed in Congo in 1961 and the 22 who died in a suicide bombing at UN headquarters in Iraq in 2003.
