The death toll following devastating flooding across France and Italy has risen to 12, as six more bodies have been discovered washed up on a shoreline.

Hundreds of rescue workers are searching for up to 20 other people who are still thought to be missing following flooding in France’s south-eastern Alpes-Maritimes region and Italy’s north-western regions of Liguria and Piedmont.

Local authorities in Italy say they have found 6 bodies on its shores. The sixth body, of a woman, was washed up in Liguria. Flooding devastated the mountainous areas after a storm swept through on Friday and Saturday. The prefect of Alpes-Maritimes told the Nice Matin newspaper that some bodies found in Italy were apparently from coffins that had been swept across the border by the raging water.
