France held a national day of mourning for Mayotte, its Indian Ocean territory devastated by a violent cyclone on Dec. 14, beginning in the morning on Monday with a minute of silence for the scores of residents left dead by the storm.

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

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