Myanmar junta hands out aid boxes with generals' names

Farmaner said the world needs to move to deliver aid directly to victims in Myanmar, also known as Burma.

"People we are speaking to in Burma say aid must be delivered anyway even if the regime doesn't give permission," he said. "We have had a week to convince the regime to behave reasonably, and they are still blocking aid. So the international community needs to wake up and take bolder steps."

However, aid providers are unlikely to pursue unilateral deliveries like airdrops because of the diplomatic firestorm that it could set off.

So far, relief workers have reached 220,000 cyclone victims, only a small fraction of the number of people affected, the Red Cross said Friday. Three Red Cross aid flights loaded with shelter kits and other emergency supplies landed Friday without incident.

But the government seized two planeloads of high-energy biscuits -enough to feed 95,000 people -sent by the U.N. World Food Program. Despite the seizure, the WFP was sending three more planes Saturday from Dubai, Cambodia and Italy, even though those could be confiscated, too.

"We are working around the clock with the authorities to ensure the kind of access that we need to ensure it goes to people that need it most," WFP spokesman Marcus Prior said in Bangkok, Thailand.

Richard Horsey, a spokesman for U.N. humanitarian operations, said an international presence is needed in Myanmar to look at the logistics of getting boats, helicopters and trucks into the delta area.

"That's a critical bottleneck that must be overcome at this point," he said in Bangkok.

He warned there was a great risk of diarrhea and cholera spreading because of the lack of clean drinking water and sanitation.

"We are running out of time here. This could be a huge problem and this could lead to a second phase which could be as deadly as the cyclone," he said.
