Seoul: South Korean authorities have banned former Defense Minister Kim Yong-hyun from leaving the country over his alleged involvement in President Yoon Suk Yeol's failed martial law declaration. The ban was imposed by the Seoul Central District Prosecutors' Office's Public Investigation Division through the Justice Ministry. According to Anadolu Agency, the development followed a complaint filed by the Labor Party, the Green Party, and the Justice Party with the Seoul Central District Prosecutors' Office. The complaint was lodged against President Yoon, Kim, and Army Chief of Staff Park An-soo, accusing them of treason. Earlier, Kim's resignation was accepted by President Yoon amid mounting criticism over his role in the failed declaration. Kim reportedly suggested that the president impose martial law and subsequently offered his resignation on Wednesday. In response to the controversy, Yoon has nominated Choi Byung-huk, a retired four-star general currently serving as South Korea's ambassador to Saudi A rabia, to succeed Kim. Yoon's Chief of Staff, Chung Jin-suk, announced the nomination at a press briefing, stating Choi is a strong candidate to maintain military readiness, emphasizing the South Korea-US alliance. Meanwhile, Army Chief of Staff Park An-su, designated as the martial law commander, informed lawmakers that he had offered his resignation to the former defense minister. During a parliamentary committee meeting, Park stated, "I understand the Department of Defense is reviewing (resignation)." President Yoon declared martial law in a live televised address on Tuesday night, only to rescind the order hours later after it was blocked by a unanimous parliamentary vote amidst nationwide protests. Following the incident, opposition parties filed an impeachment motion against President Yoon. Islamuddin Sajid and Riyaz ul Khaliq contributed to the story.
