A private plane has crashed off the Latvian coast after NATO fighter jets were scrambled to monitor its journey.
The Cessna 551 set off from Jerez in southern Spain at 1.56pm UK time without a destination specified, 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 adds.
Flight trackers show it headed northeast at Paris, towards Cologne, but went past the city and out over the Baltic Sea.
German and Danish warplanes also shadowed the plane 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, said a Lithuanian air force spokesperson.
