Three people have been pulled out alive from the rubble of their home days after Nepal's devastating earthquake, an official has said.
Other developments include:
Runway damage has forced authorities in Nepal to close the main airport to large aircraft delivering aid to millions of people following last week's earthquake.
Bigger planes had been banned because the runway was deteriorating as the huge relief effort began after the quake which has so far claimed 7,057 lives.
Birendra Shrestha, the manager of Tribhuwan International Airport, located on the outskirts of Kathmandu, said the runway was built to handle only medium-size jets and not the large military and cargo planes that have been flying to the airport.
Despite this setback, the UN coordinator for Nepal, Jamie McGoldrick, said the bottlenecks in aid delivery were slowly disappearing.
"I think the problem is there, but it's actually diminishing," he said, adding the Nepalese government eased customs and other bureaucratic hurdles on humanitarian aid following complaints from the UN.
Four men trapped under as much as 10 foot of rubble after the Nepal earthquake were rescued when NASA technology sensed their heartbeats.
One medical worker told ITV News it was like 'entering your worst nightmare' as they tried to help look after the injured.
