MUAN, South Korea — Flags flew at half-mast on Monday as South Korea mourned 179 people killed in the worst plane crash on its soil, as investigators probe why the Jeju Air plane crash-landed and burst into flames.
The country has started seven days of national mourning, with the acting president flying to the crash site in southwestern Muan for a memorial as teams of US and South Korean investigators raced to establish what caused Sunday's disaster.
