The death toll from Cyclone Chido's rampage through the French overseas territory of Mayotte remained unclear on Wednesday, with shantytowns that were home to undocumented migrants flattened and many areas still inaccessible.

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.

An overnight curfew goes into force Tuesday evening as Mayotte struggles to recover from Cyclone Chido, the strongest storm to hit the French Indian Ocean archipelago in 90 years.
