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

French President Emmanuel Macron was due on Friday to visit shantytowns in Mayotte ravaged by Cyclone Chido on the second day of a visit where he has faced calls to speed up relief to the Indian Ocean archipelago.

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.
