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:
Two more British military helicopters are to be sent to Nepal to assist the aid effort as the humanitarian mission enters a second week after the devastating earthquake.
More than 6,000 people have been killed in the worst earthquake to hit the country in 80 years, and at least 14,000 have been injured.
An RAF Chinook helicopter left Brize Norton airbase around midday yesterday, while two more will be sent out over the weekend where they will help ferry people and supplies so that humanitarian aid can be taken to those in desperate need in remote and isolated communities.
The three Chinooks, from 27 Squadron based at RAF Odiham in Hampshire, are the latest in the aid effort dispatched from the UK and follow British Army Gurkha engineers who arrived in the Himalayan country yesterday on board a C-17 aircraft, along with 18 tonnes of aid supplies that included shelter kits and solar lanterns.
International Development Secretary Justine Greening said: "These highly versatile Royal Air Force helicopters and UN aircraft will mean life-saving aid supplies can be moved around Nepal and reach people in remote communities cut off by the earthquake who are in desperate need.
"Conditions in Nepal are dire, but the UK is determined to do everything it can to help support Nepal and its people."
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.
