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.

The fire broke out in the back of the cabin, officials said. All 176 people on board, including passengers and crew members, were evacuated, some with minor injuries.

South Korea's authorities investigating last month's Jeju Air plane crash have submitted a preliminary accident report to the U.N. aviation agency and to the authorities of the United States, France and Thailand,
