Relief workers are struggling to get emergency aid through to thousands of tsunami survivors in remote districts where roads and airstrips have been washed away. In Indonesia’s Aceh province, one of the worst hit areas, it is a race against time to help the scores of people who do not have the basics to survive. US helicopters have begun shuttling injured people, many of them children, out of makeshift camps, and they are making regular food and water drops.The understandable desperation of the victims, however, has made it difficult for the pilots to distribute supplies. All they can do is appeal for calm and hope that the rations will get to as many people as possible. Officials estimate that two thirds of the 145,000 people killed across South East Asia died on Sumatra Island. There are similar scenes in coastal areas of India and Sri Lanka.
