At least 120 people have died on Sunday when a Jeju Air Boeing 737 veered off the runway and struck a wall at South Korea's Muan International Airport.

Flight 7C-2216, carrying 175 passengers and six crew members on a 4.5 hour flight from Bangkok, Thailand, was landing at the airport in the country's southwest when the crash occurred, according to Yonhap News Agency.

Firefighters now say all people on board except two rescued are presumed dead.

The crash was believed to have been caused by "bird strikes, which led to malfunctioning landing gear" during the landing attempt, Yonhap reported.

However, just recently South Korea's transport ministry says the control tower at Muan airport had sent a warning of a bird strike to the plane before the crash happened. Authorities now suspect there was a landing gear failure that caused the crash and are looking into whether a bird strike is responsible.

Footage shared by local media showed the twin-engine jet skidding down the runway without landing gear before colliding with a wall, triggering an explosion of flames and debris. Other images revealed smoke and fire consuming parts of the plane.

Acting President Choi Sung-mok, who assumed the role on Friday amid a political crisis, directed rescue efforts. "All related agencies must mobilize every resource to save lives," his office said in a statement.

A spokesperson for Jeju Air stated the airline was investigating the reports.
