SEOUL (Reuters) - South Korea's anti-corruption agency that is leading a criminal investigation into impeached President Yoon Suk Yeol's short-lived attempt to declare martial law said on Thursday it will transfer the case to the prosecutors' office for an indictment.

South Korean President Yoon Suk Yeol attended on Tuesday a Constitutional Court hearing of his impeachment trial where he denied ordering military commanders to drag lawmakers out of parliament during his short-lived bid to impose martial law.

South Korea’s impeached president has denied that he ordered the military to drag lawmakers out of the National Assembly to prevent them from voting to reject his martial law decree last month, as he appeared for the first time before the Constitutional Court that will determine his fate.

South Korea will extend runway safety areas and redesign infrastructure after the crash of a Jeju Air Co. flight last month that killed almost everyone on board, sparking criticism that the design of the airport might have exacerbated the accident.

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.
