Yoon Suk Yeol, South Korea’s since-impeached president, had been planning for months to impose martial law and target political opponents, according to accounts.

President Yoon Suk Yeol vowed to “fight to the end,” despite the opposition’s push to impeach him and his own party’s demand that he resign.

South Korea's suspended President Yoon Suk Yeol did not respond on Wednesday to a second summons by anti-corruption authorities who, along with prosecutors, are investigating his short-lived martial law decree issued early this month.
