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:
The UK has pledged a further £5m of support to the rescue effort in Nepal, bringing the total contribution to £15m.
The additional package includes:
There will also be airfield handling equipment, including two forklift trucks, to facilitate the swift movement of aid supplies off aircraft and help ease congestion at Kathmandu airport.
The UK will also fund experts in water, health and sanitation to assist the World Food Programme, Unicef and UNFPA (the United Nations Population Fund).
Announcing the additional aid, International Development Secretary Justine Greening said the UK was playing a leading role in response to the Nepal earthquake.
"We are boosting the British humanitarian effort by deploying more medics to treat the injured and delivering supplies that will help get aid through, including heavy lifting equipment to ensure supplies at Kathmandu airport can reach those in need."
