A tear runs down the face of one-year-old boy Asho as he takes refuge with his family in a camp for flood victims in the Badin district of Pakistan’s Sindh province September 20, 2011. The latest floods, triggered by monsoon rains, have killed more than 300 people, destroyed or damaged 1.4 million houses and flooded 4.5 million acres (1.8 million hectares) since late last month, officials and Western aid groups say. More than 300,000 people have been moved to shelters. Some 800,000 families hit by last year’s floods are still homeless. Aid groups have warned of a growing risk of fatal diseases.
