UN humanitarian chief John Holmes awaited Thursday a visa to travel to Myanmar where he hopes to press the junta to allow in foreign aid to help survivors of the deadly cyclone, the UN said.  As state media raised the death toll to 43,318, with nearly 28,000 still missing and another two million in dire need of help, Myanmar's southeast Asian neighbors geared up for talks aimed at convening a high-level donors meeting. UN spokeswoman Michele Montas said Holmes, who heads the body's Office for the Coordination of Humanitarian Affairs, had requested a visa "and we expect he will get it," adding he should be traveling "in the next five to six days."
