Burma's military government says more than ten thousand people may have died during Cyclone Nargis, which hit the nation on Saturday.
Officials gave the revised estimate on Monday, as information continued to come in from outlying areas.
Officials say thousands of other people are missing, while hundreds of thousands are without shelter. The prices of food and fuel have risen dramatically. The government has declared the city of Rangoon and five central and southern states (Yangon, Ayeyawaddy, Bago, Mon and Karen) disaster areas.
Some witnesses of the devastation have complained that the government is not doing enough to help survivors of the storm.
And a human rights group said today that guards at Burma's Insein prison killed 36 inmates in a prison riot after the cyclone. The Thailand-based Assistance Association for Political Prisoners said the riot started after some inmates tried to light a fire to keep warm.
Despite the upheaval, Burma's military government says a constitutional referendum will go ahead Saturday.
