A second major power outage in two days hit southeastern France Sunday, this time in the city of Nice, after an electrical facility was damaged by suspected arson. In a post on X, the mayor of the coastal city, Christian Estrosi, blamed "malicious acts." The Nice public prosecutor said a criminal investigation has been opened for "organized arson." The blackout in Nice started around 2:00 a.m. local time (0:00 a.m. GMT) and left approximately 45,000 households without electricity. The city's trams stopped, and power was briefly cut to Nice Côte d'Azur Airport during its overnight closure. According to the energy provider company Enedis, power was fully restored by 5:30 a.m. The police have not yet determined whether the blackout that affected parts of Nice and two nearby cities is linked to the power outage that disrupted the final day of Cannes' renowned film festival.
