Iran appealed for medicine and equipment to help tens of thousands hurt in Friday's devastating earthquake in the south-eastern town of Bam. The plea came as the first special international rescue teams arrived in the country to search for survivors. Estimates of numbers killed in the disaster range from 10,000 to 25,000. The Iranian authorities say more than 5,000 bodies have already been buried in mass graves, and hopes are dwindling for anyone who might be still trapped. Many thousands of people have been injured and most of Bam's buildings have been flattened, including two hospitals and the old citadel.
