UK scouts are set to leave an international event in South Korea which 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.

The British group of more than 4,000, the largest in attendance, is moving to hotels amid 35C temperatures, the Scout Association confirmed.

The South Korean government said it is sending water and medics to the site.
