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 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.
