Mayotte separated from the Comorian archipelago in 1974. Since then, the Comoros has not recognized Mayotte's membership in the France.
Operation Wuambushu aims to massively expel illegal foreigners from the island. The Comoros refused, Monday, the docking of a ship carrying sixty people from Mayotte.
