South Korea's rival parties agreed Tuesday to form a joint task force to probe the recent Jeju Air plane crash that left 179 people dead, as the transport minister offered to resign over the tragedy.

South Korea's transport minister said on Tuesday he intends to step down to take responsibility for the deadly crash of a Boeing jet operated by Jeju Air on Dec. 29.

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.
