UK scouts are leaving an international event in South Korea that has been hit by extreme heat.
Hundreds have fallen ill at the outdoor World Scout Jamboree, which is attended by more than 40,000 young people from around the world, amid 35C (95F) heat.
The British group of more than 4,000, the largest in attendance, is moving from Saemangeum to Seoul, the Scout Association confirmed.
The US and Singaporean teams are also pulling their scouts out of the event.
South Korea’s government said it was sending more medics and hundreds of helpers to maintain facilities for the many countries having to spend the next week at the camp site.
The jamboree, described as the world’s largest youth camp, gathers scouts from around the world every four years, each time in a different country.
This is the first since the pandemic and is due to run until 12 August.
The British teenagers are being put on buses back to Seoul, and will spend the next week in hotels.
One of the UK team told BBC’s Seoul correspondent Jean Mackenzie the decision to pull out was not based just on the extreme heat, but was also down to the facilities and the food.
They described toilets as a “health risk”, adding children’s dietary needs were not being met.
Many of the parents the BBC has spoken to have said their children spent years preparing to attend the event, often raising thousands of pounds to do so.
Thunderstorms are forecast for the region in which it is taking place, while temperatures will feel hotter than 40C due to high humidity, according to AccuWeather.
The World Organization of the Scout Movement (WOSM), the largest international Scouting organisation, said it had asked the Korean Scout Association, which is hosting the event, to consider ending early.
The movement said that the host “decided to go ahead with the event” and assured participants that it was doing “everything possible to address the issues caused by the heatwave”.
The WOSM called on the South Korean government to “honour” its commitments to provide extra resources and make the health and safety of participants its “top priority”.
UK Scouts, the country’s largest scouting organisation, said its group would be moved to hotels over the next two days to “alleviate the pressure on the site overall”.
It added that its volunteers and others had worked to give their members “enough food and water… shelter from the unusually hot weather… and toilets and washing facilities appropriate for an event of this scale.”
The group will travel home on 13 August as planned.
The UK and US teams have the money and resources to relocate thousands of people at short notice but there are plenty of countries at the event which do not.
The United States has also decided to withdraw its participants and take them to an army garrison in Pyeongtaek, citing safety concerns.
Parents of children at the campsite told the BBC that no activities were taking place due to the heat, and some people with specific dietary requirements were not being catered for.
Others have defended the event, saying their children were disappointed that they had to leave.
One mother from the north-east of England said that what was meant to be a “great life experience” had turned into a “survival mission” for her 16-year-old daughter.
“She knew it would be hot but not as hot as it is. They cannot cool down, their tents are too hot,” said the mother, who did not wish to be named.
Her daughter had told her that the showers and toilets were “appalling and unsafe”, with “floating rubbish, plasters and hair” blocking drains.
She said she was delighted that her daughter was being moved to Seoul, which is about 120 miles (197km) from the campsite.
Another parent said the situation was so bad they put their daughter on a plane back to the UK on Friday. “My priority was my daughter’s welfare,” they said.
However Peter Naldrett told the BBC that his two children were “frustrated, upset and angry” about having to leave.
“My kids have said that the toilets are a bit grim but it’s manageable,” he said.
Shannon Swaffer, whose 15-year-old daughter is at the event, said the children were “all devastated that it’s ended early”.
“By all accounts the heat is intolerable and adults and kids alike can’t continue there,” she said, adding that her family were “lifelong Scout people” and that the leaders had been “absolutely phenomenal”.
Rebecca Coldwell said her 17-year-old daughter had received “outstanding” medical care for an infected wound, and that she was “heartbroken” about having to move to hotels.
Kristin Sayers from Virginia in the US, paid $6,500 (£5,100) for her 17-year-old son Corey to go to the jamboree but said his dream had turned into a “nightmare”.
“He’s very aware of how much money that is and the sacrifices we made as a family to send him. We could’ve done so much with that money,” she told Reuters news agency.
UK Scouts has been asked for comment regarding claims of poor sanitation.
The Foreign Office said on Thursday that it had officials on the ground supporting British scouts.
South Korea is experiencing a sweltering summer and authorities have issued the country’s highest hot weather warning for the first time in four years.
The majority of those attending the camping event are aged between 14 and 18. There are groups from 155 countries.
Officials told Reuters that at least 600 people had been treated for heat-related illnesses in recent days. Their nationalities were not specified.
South Korean Prime Minister Han Duck-soo announced that aid was being sent to the site amid criticism from some that authorities failed to plan for extreme heat.
“The government will use all its resources to ensure that the jamboree can end safely amid the heatwave,” he said.
Air-conditioned buses, water trucks and medical staff were being dispatched.
