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.

South Korea's acting President Han Duck-soo has been impeached by the opposition party controlling the National Assembly. This comes weeks after President Yoon Suk Yeol's imposed martial law, leading to his own impeachment.

South Korea’s President Yoon Suk Yeol again declined to appear for questioning by investigators over his martial law declaration as the embattled leader seeks to first defend himself at an impeachment trial.
