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.

French authorities believe arson may have played a role in a major power outage that threatened to jeopardize the Cannes Film Festival’s closing celebrations.

A major power outage struck France's Alpes-Maritimes region, including Cannes, during the final day of the prestigious film festival. Authorities suspect arson after a fire at an electrical substation and damage to a pylon.
