South horea crisis deepens as Yoon faces probe over imposition of martial law

South Korea's political crisis intensified after President Yoon Suk Yeol survived an impeachment vote on Saturday, with the prosecutors' office reported to have opened an investigation into his role in last week's brief imposition of martial law and arrested the former defence minister in connection with the declaration.

Park Se-hyun, chief of the Seoul High Prosecutors' Office, opened the probe into Yoon after receiving several complaints, according to Yonhap News. The report followed the arrest hours earlier of ex-defence minister Kim Yonghyun.

Yoon's office could not immediately comment on the report, while the prosecutors' office was not available for comment.

The investigation marks a dramatic turn of events for Yoon, a former prosecutor who made his name pursuing an influence-peddling case that involved former president Park Geun-hye—who was ultimately impeached and jailed.

The effects of the martial law declaration were still being felt on Sunday, with interior minister Lee Sang-min quitting because of the turmoil.
