France marked a day of mourning Monday for victims of Cyclone Chido, which devastated its poorest territory, Mayotte, over a week ago.

Cyclone Chido not only ravaged Mayotte’s infrastructure but also laid bare tensions between the island’s residents and its migrant population.

France has held a national day of mourning for the victims of Cyclone Chido, which devastated the French overseas region of Mayotte earlier this month. The cyclone was the most destructive to hit Mayotte in 90 years and caused extensive damage to the island off Africa’s east coast.

The death toll in the French territory of Mayotte from Cyclone Chido is “several hundred” and may run into the thousands, the island’s top government official told a local broadcaster Sunday.

Hundreds are feared dead after the storm razed entire neighborhoods in Mayotte, a series of islands off the eastern coast of Africa, before unleashing its destructive force on Mozambique.
