A Burmese Air Force fighter plane crashed Friday morning while attempting to land at Rangoon airport, killing its pilot, an airport official said.

An official at Rangoon International Airport said the Chinese-made F-7 jet crashed while on a training flight. The official spoke on condition of anonymity because he was not authorized to speak to the press.

The cause of the crash was not immediately known. The Air Force base is adjacent to the civilian airport and uses the same runways.

According to the Stockholm International Peace Research Institute, a Swedish think tank, Burma purchased at least 36 F-7 jets from China in the 1990s.
