Prosecutors indicted detained South Korean President Yoon Suk Yeol on Sunday on charges of leading an insurrection with his short-lived imposition 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 looks set for a dramatic political showdown this week as impeachment proceedings kick off against suspended President Yoon Suk Yeol, who remains holed up in his fortified residence evading arrest for a separate criminal investigation.
