Reports say heavy floods have forced the evacuation of 1 600 people – most of them campers in southern France.

They say a 70-year-old German man who was helping to supervise children at one of the summer camps is missing.

Trapped by a fast-flowing torrent, he sought shelter inside his caravan – but the vehicle was swept away, the AFP News Agency reports.

The flooding comes after southern France – and much of Europe – experienced unusually hot weather.
