London - International aid organizations working in Myanmar Tuesday compared the scale of the cyclone to the suffering caused by the 2004 Indian Ocean tsunami.
Hundreds of thousands of people had been left without shelter or clean drinking water, charities said.
"People are saying this is worse than the (December 26, 2004, Asian) Tsunami. It's like a war zone. The number of dead is just staggering," James East, of the charity World Vision, said.
East, speaking to Britain's GMTV station from Bangkok, Thailand, said: "Water is running out. The government has asked us to supply water purification tablets and units. We want to do that as soon as possible. The children are the most vulnerable."
