Authorities in the French overseas territory of Mayotte could still confirm only 31 deaths on Wednesday from Cyclone Chido, more than four days after it swept through the Indian Ocean archipelago, causing mayhem and killing possibly thousands.

Authorities in Mayotte were racing on Tuesday to stop hunger, disease and lawlessness from spreading in the French overseas territory after the weekend’s devastating cyclone, while Mozambique reported dozens of deaths from the storm.

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.
