Authorities will start a joint investigation into the Air Busan A321 that burst into flames at Busan Gimhae International Airport, Yonhap News Agency reports.

It is a month since the deadliest air disaster on South Korean soil when a Jeju Air plane coming from Bangkok crashed on Muan Airport's runway as it made an emergency belly landing, killing all but two of the 181 people and crew members on board.

South Korean officials are launching an investigation into the cause of the fire that engulfed an Air Busan passenger plane, with eyewitness accounts suggesting a power bank may have sparked the blaze.
