SEOUL, Dec 29 (Reuters) - At least 28 people were killed

when an airliner went off the runway and slammed into a wall at

South Korea's Muan International Airport on Sunday, Yonhap news

agency reported.

The accident occurred as Jeju Air flight 7C2216, carrying

175 passengers and six crew on a flight from the Thai capital

Bangkok, was landing at the airport in the south of the country,

the report said.

Two people were found alive and rescue operations were still

under way, a Muan fire official said. The official could not

confirm the reports of 28 dead.

Authorities were working to rescue people in the tail

section, an airport official told Reuters.

Video shared by local media showed the twin-engine aircraft

skidding down the runway with no apparent landing gear before

slamming into a wall in an explosion of flame and debris. Other

photos showed smoke and fire engulfing parts of the plane.

Aviation tracking site FlightRadar24 said the aircraft

appeared to be a Boeing 737-800. Boeing ( BA ) did not immediately

respond to a request for comment.

The U.S. Federal Aviation Administration did not immediately

respond to an email seeking comment.

South Korean acting President Choi Sang-mok, who was named

interim leader of the country on Friday after the previous

acting president was impeached amid an ongoing political crisis,

ordered all-out rescue efforts, his office said.

His chief of staff convened an emergency meeting.

A Jeju Air spokesperson said the airline was checking the

reports.
