French authorities have deployed about 1,000 firefighters, four military helicopters and troops to search for at least nine people who are missing after devastating floods from record rains hit a mountainous border region with neighbouring Italy. Al Jazeera quotes Nice Mayor Christian Estrosi as saying it was the worst flooding disaster in the area in more than a century with “the roads and about 100 houses […] swept away or partially destroyed”. About 10,500 homes were left without electricity, French energy company Enedis said, while the government declared the region a natural disaster zone.
