A light aircraft crashed at Gimpo International Airport in western Seoul, sources said Sunday, killing two on board after losing communication shortly after takeoff.

Firefighters said the plane crashed in a field within airport grounds around 6:32 p.m., killing the only two people aboard, including the pilot.

Seoul Regional Office of Aviation said the cause of the crash has not been identified. The plane belongs to Halla Sky, a local pilot school.

Other flights at the airport are operating as scheduled, they added.

State-run Korea Airports Corporation said it opened a special investigation team immediately after the crash. (Yonhap)
