A private plane has crashed off the Latvian coast after fighter jets from across Europe were scrambled to follow its journey.
The Cessna 551 set off from Jerez in southern Spain at 1.56pm UK time, according to FlightRadar24 data.
German news site Bild said it was supposed to land at Cologne Bonn Airport but reported pressure problems in the cabin shortly after take off.
French and Spanish fighter jets were sent up, but couldn’t see anyone in the cockpit or cabin, Bild added.
A family of three and a pilot were reportedly on board.
Flight trackers show it headed northeast at Paris, towards Cologne, but the aircraft went past the city and out over the Baltic Sea.
German and Danish warplanes also shadowed it as it passed through their airspace, but were unable to make contact, said Swedish Maritime Administration official Johan Wahlstrom.
NATO jets from the Baltic Air Police mission in Estonia also took up the chase, according to a Lithuanian air force spokesperson.
The plane passed close to the Swedish island of Gotland, but FlightRadar24 lists it as rapidly losing altitude and speed at 6.37pm.
Sweden’s rescue service said it “disappeared from radar” and crashed in the sea northwest of Ventspils in Latvia.
An air force helicopter and naval ships from Lithuania have been deployed, with a Stena Line ferry also said to be on the way.
The plane was registered in Austria.
The Cessna 551 is a 14-metre long single-pilot jet that can carry six to eight passengers.
