15-year-old boy has been rescued from the rubble of a building in Kathmandu, five days after an earthquake that killed at least 5,500 people in Nepal.
Pemba Lama told the BBC he survived by drinking water from wet clothes and eating pots of clarified butter. He was taken to a field hospital.
Meanwhile, bad weather is hampering the delivery of relief to remote villages, a Nepali government spokesman said.
The government has been criticised for its response to the disaster.
Outside Kathmandu, the relief effort has relied heavily on helicopters, with mountain roads blocked by landslides triggered by the earthquake.
Laxmi Dhakal, a spokesperson for Nepal's home ministry, told the BBC that helicopters had been held back by "rainfall and cloudy conditions".
