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.

Power was restored hours before the ceremony, around 3 p.m. local time, as music began blasting again from beachfront speakers.

An arson attack and damage to a transmission tower cut off power in the area, the authorities said. The festival’s closing ceremony on Saturday is scheduled to proceed normally.
