A major power cut across southern France left around 160,000 homes without electricity on Saturday and impacted the town of Cannes, which is currently hosting its annual international film festival.

a power outage, apparently caused by deliberate sabotage, shut down the power grid serving the city and much of the surrounding region.

Prosecutors say a first power cut occurred when a substation in the village of Tanneron, which supplies Cannes, was attacked by arsonists in the early hours.
