1,500 missing after glacial collapse in Nepal and Tibet

Nearly 1,500 people, including at least 800 foreigners are missing across Nepal and China's Tibet, authorities said on Thursday, after a wall of mud and rock collapsed into a Himalayan river, sending catastrophic floods through towns and valleys.

Rescuers in Nepal used helicopters to search for survivors and drop emergency supplies to thousands cut off after Wednesday's disaster swept a rugged mountainous region thronged by trekkers and pilgrims linking Lhasa in Tibet with the Nepalese capital of Kathmandu. Police said they expected the death toll to rise beyond 165.
