As many as 41,000 people were listed as missing by the military junta ruling the country formerly known as Burma, The Daily Telegraph reported.

Maung Maung Swe, Myanmar's social welfare minister, said most of the town of Bogalay, was washed away, killing more than 10,000 people.

U.N. Secretary-General Ban Ki-moon said the United Nations "will do whatever (is necessary) to provide urgent humanitarian assistance."

The United States initially made available $250,000 through its embassy in Myanmar for non-government organizations and U.S. President George Bush said Tuesday the United States was poised to do more.

"The military junta must allow disaster assessment teams into the country," Bush said Tuesday when signing legislation awarding the Congressional Gold Medal to Nobel Peace Prize laureate Aung San Suu Kyi, the Myanmarese pro-democracy leader under house arrest for 12 years. "Our message is to the military rulers is: Let the United States come to help you, help the people."

Despite the disaster, the junta plans to have Saturday's constitution referendum, which critics see as a ploy to kept the military in power.
