A group of scouts from Switzerland were in a bus accident as they were being evacuated from the World Scout Camp in South Korea.
None of the scouts were injured, but 10 others had to be taken to hospital.
The international scout Jamboree is held every four years. The camp had already been hit by a heatwave and authorities had been bringing in air-conditioned buses and extra water.
But the arrival of a hurricane forced the 40,000 participants to leave.
Nearly 1,500 scouts from Switzerland were at the Jamboree.
