South Korean investigators asked prosecutors to indict the country’s detained President Yoon Suk Yeol over his short-lived imposition of martial law last month, as it accused him of rebellion, abuse of power and obstruction of parliament.

South Korean President Yoon Suk Yeol appeared in a Seoul court for his impeachment trial Tuesday, defending his short-lived martial law bid and denying charges that he ordered the military to drag lawmakers away.

Yoon Suk Yeol has faced South Korea's constitutional court for the first time, following last month's martial law saga.
