The French civil aviation authority says Argentine soccer player Emiliano Sala was aboard a small passenger plane that went missing off the coast of the island of Guernsey.
French and British maritime authorities are searching the English Channel for the plane.
Guernsey police say the flight left Monday evening from Nantes en route to Wales with two people aboard. Police say the search resumed Tuesday morning and that no trace has currently been found. The French regional maritime authority sent a search helicopter.
The 28-year-old Sala, who has been playing for French club Nantes, signed for Premier League team Cardiff on Friday for a club record fee.
