Yangon: Two more US aid flights were due to leave for cyclone-hit Myanmar on Tuesday where aid deliveries to survivors are minimal so far.

The White House also said it is offering $13 million (Dh47.75 million) in aid to UN agencies.

"We hope that this is just the beginning of what will be much-needed assistance that we are happy to provide," said White House spokeswoman Dana Perino.

Medicins Sans Frontieres said its first cargo plane loaded with medical supplies landed in Yangon on Monday but it was facing "increasing constraints" imposed on its staff.

Tens of thousands of people throughout the country are crammed into monasteries, schools and other buildings and aid workers say they do not have enough supply for everyone.


The junta has welcomed "aid from any nation" but has made it very clear it does not want outsiders distributing it in the areas worst hit by Cyclone Nargis, which struck 11 days ago.

Speaking after the first US military aid flight to Myanmar on Monday, US President George W. Bush condemned the junta for failing to act more quickly to accept international help, saying "either they are isolated or callous."

"It's been days and no telling how many people have lost their lives as a result of the slow response," he said in a radio interview with CBS News.
