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.

Yoon’s detention, after a tense standoff outside the presidential residence, marks the latest chapter in a bewildering series of events since his martial law decree.
