Officials are investigating the cause of the deadliest aircraft crash in South Korean history, which killed 179 people.

The flight, operated by Jeju Air, was landing when it went off the runway in Muan, in the country’s southwest. Only two people survived the crash.

Just two survivors were rescued from the wreckage of the passenger plane, which had been returning from Thailand.

Investigators from the NTSB and Boeing were expected to join the investigation into South Korea's deadliest air crash.

Acting South Korean President Choi Sang-mok has told emergency responders to use "all available" resources to respond to the crash.

A plane carrying 181 people crashed while landing, killing most on board. Officials were investigating a possible malfunction with the landing gear and a bird strike.

Families wept and wailed as officials read off the names of the victims who died on Sunday, Dec. 29, at Muan International Airport, where the crash occurred.

The flight was carrying 181 passengers and crew when it belly-landed before slamming into a barrier, killing all aboard except two flight attendants.

South Korean police on Thursday, January 2, raided Jeju Air's regional aviation office, the office is in Seoul, and the crash site as a part of the ongoing investigation, reported the news agency AFP.
