South Korean President Yoon Suk Yeol attended on Tuesday a Constitutional Court hearing of his impeachment trial where the detained leader may get a chance to argue his case or answer questions over his short-lived bid to impose martial law.

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 denied wrongdoing as he branded himself as a firm believer in democracy in his first appearance at an impeachment trial looking into his shocking and brief imposition of martial law last month.
