Authorities in Afghanistan say more than 200 people are missing and feared dead in floods caused by days of torrential rain.

The worst hit areas were in Deh Rawud district in central Uruzgan province and western Herat province. Police say floodwaters from the Helmand, Afghanistan's longest river, destroyed thousands of homes.

U.S. military helicopters rescued about 200 people who were marooned by the floods, and American troops and U.N. workers have been distributing emergency relief supplies to survivors.

Afghan officials are bracing for more serious flooding in the days ahead. More rainstorms are expected, and warmer weather has been melting deep snow left by one of the country's harshest winters in years.
