A 64-year-old nursing assistant swept away in her car remains unaccounted for, along with a man who went missing during a hill run in the Cevennes.
Emergency services have mobilized helicopters and 700 personnel to assist inhabitants hit by the flooding, which has also cut off road access, water and electricity supplies to some locations.
Interior Minister Gerard Darmanin, who travelled to the affected region on Sunday, said some 50 people had been rescued from the flood waters and another 420 given emergency shelter. (Reporting by Blandine Henault; Writing by Laurence Frost Editing by Gareth Jones)
