France was rushing help by ship and military aircraft to its poor overseas territory of Mayotte in the Indian Ocean on Monday after the island was shattered by its worst storm in nearly a century.

Authorities in Mayotte fear hundreds and possibly thousands of people have died in Cyclone Chido, although the official death toll on Monday morning stood at 14. Rescue teams and medical personnel have been sent to the island off the east coast of Africa from France and from the nearby French territory of Reunion, as well as tons of supplies.
