News reports said a small aircraft that crashed in northeast China may have been a North Korean fighter jet.
Beijing's official Xinhua news agency said the aircraft went down Tuesday in Fushun County, located in Liaoning province. An unnamed government source told Xinhua the jet "might be" a North Korean plane. Xinhua did not identify the pilot or the aircraft.
South Korea's Yonhap news agency said intelligence sources believe the aircraft appeared to be a Soviet-era jet fighter, after earlier reporting said it may have been a helicopter. The anonymous sources said the pilot could have lost his way while flying to Russia.
Yonhap said the pilot, who was the only person on board the aircraft, was killed.
Fushun is located about 150 kilometers from the North Korean city of Sinuiju, where a military airbase is located.
