A Jeju Airlines airplane veered off the runway upon landing in South Korea and collided with a concrete wall, killing at least 23 in a dramatic fireball, after its landing gear malfunctioned following what aviation authorities say was a likely bird strike.

The flight, yet another unfortunate Boeing 737 aircraft, was carrying 175 passengers and 6 crew members to Muan International Airport, in the country’s south. It was returning from Bangkok, according to the news agency and Flightradar24 data. The 737 plane in question was not a Max jet.

The incident is suspected to have been caused by a landing gear malfunction following a bird strike, according to the local fire department.

The Korean transport ministry said it was investigating the crash. The airline and the fire department were not immediately available for comment.

The fatal crash takes place just days after a Dec. 25 crash involving an Azerbaijan Airlines passenger plane, killing dozens.
