COLOMBO: Foreign aid began arriving in Sri Lanka Saturday, bringing help to half a million people who have been driven from their homes by heavy rains and landslides that have killed at least 71. The heaviest rains in a quarter of a century have pounded Sri Lanka since last weekend, triggering huge landslides that have buried some victims in up to 50 feet (15 meters) of mud. The number of people missing now stands at 127. Floodwater levels in parts of the capital subsided slightly overnight, officials said, but heavy downpours on Saturday prevented many from moving back to their homes on the banks of the Kelani river. Nearly 300,000 people were staying in about 500 state-run relief centres on Saturday, which also marks Vesak, a Buddhist holiday.
