CANNES, France (AP) — Sudden heavy rains in and around the French Riviera have killed at least 13 people, including some trapped in cars and in a retirement home.

French President Francois Hollande said in a statement that people were found dead in the towns of Cannes, Biot, Golfe-Juan and Mandelieu-la-Napoule in the southeast, not far from Italy. He said the rains Saturday night also caused serious damage.

Interior Ministry spokesman Pierre-Henry Brandet said the death toll had reached 13 on Sunday morning, including some victims who had been trapped in a parking lot and some in a retirement home. The exact circumstances of the deaths were unclear.

More than 17 centimeters (6.7 inches) of rain fell on the Cannes region in two hours, local radio France Bleu-Azur reported.
