French Prime Minister François Bayrou believes dozens of people died after the cyclone hit the territory, rather than thousands.

France is holding a national day of mourning for Mayotte, its Indian Ocean territory devastated by a deadly cyclone on Dec. 14, on Monday, beginning with a minute of silence at 11:00 a.m. (1000 GMT).

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