The prosecution imposed a travel ban on Former Defense Minister Kim Yong-hyun on Thursday as part of an investigation into treason charges related to this week's failed martial law declaration, APA reports citing Yonhap.
Yoon declared martial law on Tuesday night at Kim's suggestion amid an intensifying political deadlock with the opposition-controlled National Assembly. He reversed the order six hours later after the Assembly voted to end it.
Kim tendered his resignation and Yoon accepted it Thursday.
