South Korea's government said on Monday it will extend the shutdown of Muan International Airport by a week to Jan. 14, citing the ongoing investigation into the crash of a Jeju Air jet that killed 179 passengers on board.

After overcoming pariah status at the end of the last century, South Korea must learn what caused the catastrophe on Dec. 29 and what lessons to draw from it.

South Korean authorities have extended the closure of a southwestern airport where a Jeju Air plane crashed and killed 179 people onboard, the land ministry said Monday. Authorities are still probing the cause of the accident on December 29,
