About 30 people at a French rave had to be treated for hypothermia after it unexpectedly snowed.
People at Teknival, a techno music festival in the central Creuse region, were exposed to the elements when temperatures dropped to -3C (27F).
About 10,000 people were gathered on a military-owned hill top when it started snowing heavily.
Rescuers from the Red Cross treated most of those affected at the scene, but two had to be taken to hospital.
They also gave out 500 survival blankets while organisers set up a heated tent at the site, Agence France Presse news agency reported.
