The official death toll from Cyclone Nargis has nearly doubled to almost 78,000 and another 56,000 people remain missing two weeks after the storm, Myanmar state television reported Friday.

The United Nations, meanwhile, said that severe restrictions by Myanmar's military junta have left aid agencies largely in the dark about the extent of survivors' suffering.

John Holmes, U.N. undersecretary-general for humanitarian affairs, will go to Myanmar on Sunday in an attempt to convince junta leaders to grant more access to U.N. relief workers and massively scale up aid efforts, said Amanda Pitt, a U.N. spokeswoman in Bangkok, Thailand.

With pressure mounting, the military regime has invited foreign diplomats to tour the hard-hit Irrawaddy delta on Saturday, providing their first opportunity to personally view the devastation.

U.S. Embassy charge d'affaires Shari Villarosa told The Associated Press Friday that the Foreign Ministry was arranging the trip, but no further details were available and it was unclear how much access the diplomats will have outside the controlled tour.The handful of foreign experts who have been allowed into the country have been restricted to Yangon, the former capital. The government has set up police and military checkpoints on roads leading out of Yangon to Irrawaddy, where foreigners are being turned back.

The Red Cross fears the cyclone toll may be as high as 128,000; the U.N. estimates more than 100,000 died. The U.N. estimates 1.5 million to 2.5 million survivors are in desperate need of food, water, shelter and medical care. Aid groups have reached only 270,000 so far.

"The risk increases with each passing day," Pitt said, referring to the vulnerability of survivors to outbreaks of disease and other problems.

Lack of clean water will be "the biggest killer" in Irrawaddy in the coming days, Thomas Gurtner, the head of operations for the international Red Cross, told The Associated Press in Geneva.

"To be able to provide clean water to hundreds of thousands of people stranded in the (Irrawaddy) delta requires a major operation, which we have neither the material, the logistical nor the staff capacity to do," he said.

The U.N. health agency said Friday it was concerned about diarrhea, malaria and dengue fever spreading among the cyclone victims.
