A British national has been killed in the Nepal earthquake.
The announcement comes as a stranded British woman remains in an area of the devastated country where falling rocks are still killing people.
The Foreign Office confirmed the death of a non-resident British national and said they are in contact with the family.
Meanwhile, Susannah Ross, 20, from Bath, is among a group of trekkers left stranded in the Langtang valley in the north of the country and she is not expected to be rescued until Thursday at the earliest, her sister said.
Nina Ross said they received a satellite message at about 5am saying the group is still awaiting rescue and she called for pressure to be put on authorities to act.
Asked how she had found her experience of communicating with the British embassy and authorities in general, Nina, 25, said it had been “very frustrating”.
She said the stranded group flattened some land so there is a helicopter landing pad, but they have been told that Susannah may not be rescued until tomorrow.
“We’re really hoping to get through to different embassies to hurry it up because there’s still falling rocks in that area that are killing people,” she said.
Nina said she has not spoken to her sister directly, and added: “We really need pressure on the embassies, on any kind of charities, on anyone, to get helicopters out there.”
She said people from other countries were lifted out yesterday as their embassies had paid for helicopters.
“So the British embassy haven’t paid for helicopters to get Susannah out and that means that she’s been left there with some people,” she said.
Nina said they had indicated they would launch a rescue attempt today but she said they “changed their mind” and are not sending a helicopter today.
She said that, due to this, the family “don’t really trust that they are sending one tomorrow”, and said she did not know how much food or water the group had left.
A number of other families of British and Irish people are still awaiting news of their loved ones who might have been in the region at the time of the massive earthquake.
Nepal’s prime minister Sushil Koirala has said the death toll could eventually double.
A medical student from a British university, American Dr Marisa Eve Girawong, was among those killed in avalanches on Everest.
Meanwhile, British personnel have arrived in Nepal to help with the overall rescue operation as medical services are at “breaking point” after thousands were killed.
A team of more than 60 UK international search and rescue responders and specialist rescue dogs have arrived, with some already operating on the ground and travelling out of the capital to more remote areas, the Department for International Development (DfID) said.
The personnel are drawn from 15 fire and rescue services from across the UK, and their capabilities include locating deeply-buried victims, constructing timber supports to safely shore up buildings and providing advanced life support.
They were joined by an eight-strong group of expert trauma medics, and more UK medical crews are expected to arrive in the country in the coming days.
Rob Holden, head of the UK emergency medical team said: “We are hearing a lot of reports from the ground that there are thousands of survivors with trauma injuries who urgently need surgery – worryingly, this includes the most vulnerable of society such as women and children.
“This massive earthquake has stretched medical services in an already impoverished nation to breaking point – doctors have been forced to operate around the clock and often in makeshift hospitals made of tents.”
The British public have been urged to do what they can to help in the wake of Saturday’s 7.8 magnitude quake, with a televised appeal reminding people of the sacrifices made by Nepalese Gurkha soldiers as part of the British Army in decades past.
Eight million people have been affected, according to the United Nations, by a disaster which wiped out entire villages and has so far claimed the lives of more than 5,000 people.
British aid to Nepal now totals £15 million, and Foreign Secretary Philip Hammond said the Foreign Office is continuing to work to help identify and help British nationals in the region.
In a televised appeal on behalf of the Disasters Emergency Committee, actress and Gurkha campaigner Joanna Lumley said: “My father served with the Gurkhas, who for 200 years have sacrificed their lives for Britain. Now it’s our turn to help their country.”
Members of the Nepalese and Gurkha community in the UK have spoken of their sense of helplessness at watching the “heart-wrenching” images on television.
The UK has already pledged a £5 million package of support, including £3 million released under the Rapid Response Facility to address immediate needs on the ground and £2 million to the British Red Cross.
Disaster experts believe the earthquake will leave Nepal dependent on aid from countries such as the UK for years, and recovery from the devastation could take a decade.
