Yonhap news agency says South Korean prosecutors have indicted the impeached President Yoon Suk Yeol over his imposition of martial law.

President Yoon Suk Yeol will stand trial along with his former defense minister and others who participated in his short-lived imposition of martial law.

South Korean President Yoon Suk Yeol's term in office has been dogged by personal scandals, an unyielding opposition and rifts within his own party, and a rapid fall from grace over his short-lived declaration of martial law last month.
