South Korea's transport ministry said on Wednesday that it would remove the concrete embankment installed at Muan International Airport following last month's Jeju Air crash, its deadliest domestic air disaster.

The government on Wednesday announced a comprehensive plan to address potential risks associated with emergency landings at airports across the country following last month's deadly Jeju Air accident.
