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

Nearly 45,000 people suffered a power outage in and around Nice, southern France on Sunday, after an electrical transformer was set on fire overnight, according to the city’s mayor.

French police were investigating a possible arson attack as being the main cause for a power outage which hit the Alpes-Maritimes region in southern France on Saturday, including Cannes which is hosting its world-famous annual film festival.
