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.

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

South Korea's Yoon Suk Yeol rose from star prosecutor to the presidency in just a few years, but after a series of scandals and a bungled martial law decree, he's become the country's first-ever sitting president to be arrested.
