About 70 per cent of Myanmar's hungry cyclone survivors remain without UN food aid more than two weeks after the disaster, forcing them to leave their villages, relief workers said on Monday. With the junta so far resisting calls to allow enough foreign disaster experts in to help direct the emergency effort, supplies are stacking up in Yangon with only small trucks to get aid to some two million needy people. Marcus Prior, spokesman from the UN's World Food Programme, said while 750,000 survivors were in desperate need of food, only 250,000 people had been reached with a two-week ration of rice.
