Stricken Myanmar seeks international aidYANGON, Myanmar (CNN) -- Myanmar's ruling military junta was expected to issue a rare request for international emergency assistance Monday as more details emerged of the scale of the humanitarian crisis facing the cyclone-stricken southeast Asian country.
The Associated Press reported that resident ambassadors had been summoned to a foreign ministry meeting after a state of emergency was declared across much of the country following the 10-hour storm that left at least 350 people believed dead and swathes of devastation in its wake.
The government of neghboring Thailand said Myanmar's leaders had already requested food, medical supplies and construction equipment, AP reported. The first plane-load of supplies was due to arrive Tuesday, a Thai spokesman said.
Scenes of the destruction showed flooding, roofs ripped off buildings, uprooted trees and downed power lines after cyclone Nargis battered the Irrawaddy delta throughout Friday night and Saturday morning.
"After about noon, the sky cleared and everybody came out and were just stunned," said Shari Villarosa, U.S. Charge D' Affaires in Yangon. "People on my compound who had been there for about 15 years say they had not seen anything like this here, ever."
Residents of Yangon trudged through knee-deep swirling brown waters Monday as the delta city remained mostly without electricity and phone connections. Watch the cyclone hammer Yangon »
A spokesman for the Red Cross said the emergency aid group was working with its Myanmar agency to provide drinking water, temporary shelters and blankets and warned that urgent action was needed to limit outbreaks of disease.
"I think one of the biggest needs right now is to stave off disease," said spokesman Eric Porterfield. "We will be helping with the distribution of clean drinking water and setting up shelters."
Relief agencies met at the United Nations' Bangkok headquarters Monday to coordinate their response to the disaster. The International Federation of Red Cross and Red Crescent Societies said it had released 200,000 Swiss Francs (about $190,000) to help with the aftermath.
At least 350 people are estimated to have died as a consequence of the storm, according to state media reports. But there are fears that the full scale of the disaster may have been concealed by Myanmar's brutal authoritarian regime.

"They don't want to admit that they are incapable of taking care of their own people," Larry Jagan, a freelance journalist who has covered Myanmar affairs for many years, told CNN.
"So I think they will be slow in responding to international offers of aid. And the international community cannot, of course, move until there is some official statement from the government."
"We believe hundreds of people are dead," said Khin Maung Win with the Democratic Voice of Burma -- a broadcast media group run by opposition expatriates. "The entire lower Burma is affected. In some areas, entire villages disappeared."
The activist group opposes military rule in Myanmar, formerly known as Burma.
The ruling junta declared a state of emergency in five regions: the city of Yangon, Irrawaddy, Pegu and the states of Karen and Mon. All flights to Yangon, the former capital, were canceled.
"Most Burmese with whom we've been in touch report they lost their roofs, although so far everyone we have been able to contact reports that they and their families are safe," said a Yangon-based diplomat who requested anonymity because he was not authorized to speak to the media.
Earlier Monday, an editor for an independent Myanmar newspaper based in Thailand told CNN that people in the Southeast Asian nation were angry over the response to the disaster by the ruling military junta.
"People are very angry with the slow response coming from the military government," said Aung Zaw of Irrawaddy news magazine.
Zaw said communication was down across large areas of the country. He also said the casualty figures could rise.

Pictures from inside the country showed a cyclone-ravaged region with tin huts crushed under trees. Bicyclists navigated around large branches that littered the deserted roads.
A man with his pant legs rolled up waded through knee-deep water and strained to clear massive limbs that were blocking the entrance to a house.
"The cleanup is beginning, but this will take a long time," the diplomat said. "The damage around town is intense." See photos of the destruction »
"Fuel is not easily available. International emergency assistance would be needed within seven days. There is no food for eating," Win said.
Food prices -- already rising steeply -- climbed further. Long lines could be seen at gas stations in Yangon. Many of the stations were operating on generators. At one gas station more than 100 buses lined up to refill.
"International emergency assistance would be needed within seven days," the diplomat said.
Despite widespread damage, Myanmar's junta plans to proceed with a referendum on the country's constitution on May 10 -- the fourth step of a "seven-step road map to democracy" -- according to state-run media reports.
The government has said elections would be held in 2010 to choose a representative government to replace the military junta.
An official at the Myanmar consulate in Canberra, Australia, said she believed the referendum would go on as scheduled. "We haven't had contrary information," she said.
But the announcement was met with skepticism from pro-democracy opposition leaders.
"It looks as though it would be impossible to have a referendum on Saturday in those areas," said Jagan, the analyst.
"The question is, will the regime decide to postpone the referendum in those particular areas, and hold it in other parts of the country?. Or will they go ahead and hold it anyway, and do the best they can?"
Myanmar last held multi-party elections in 1990, when Aung San Suu Kyi's National League for Democracy handily won. The military junta ignored the results. Suu Kyi, who is currently under house arrest, has been in detention without trial for more than 12 of the past 18 years.
