South Korean prosecutors charged President Yoon Suk Yeol for his failed attempt last month to place the country under martial law, forcing the impeached leader to remain in detention as they build a case against him.

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