Out of more than 1,400 injured, 45 people are in need of emergency medical aid, the broadcaster added.
On Sunday, Mayotte Prefect Francois-Xavier Bieuville said that nearly 1,000 people could have died after Cyclone Chido hit the French archipelago in the Indian Ocean. The prefect said it was "extremely difficult" to establish an exact number of victims at the moment. On Tuesday, the local authorities introduced a curfew from 10:00 pm to 4:00 am local time (19:00-01:00 GMT).
It was the strongest storm to hit Mayotte in at least 90 years, Meteo-France has said.
On Thursday, French President Emmanuel Macron traveled to Mayotte to evaluate the damage caused by the cyclone. As rescue teams hurried to find survivors and deliver much-needed assistance, Macron's flight brought in around 20 medical and civil security staff, along with four tonnes of food and hygiene supplies, media reported.
Mayotte lies in the southwestern Indian Ocean, off the coast of Africa. It is considered the poorest French department.
