South Korean authorities have granted a request to extend a warrant to detain the country’s suspended President Yoon Suk Yeol for questioning over his surprise declaration of martial law last month.

South Korean President Yoon Suk Yeol's security chief said on Friday the impeached leader, who faces arrest over a criminal probe into his Dec. 3 martial law bid, has been unfairly treated for a sitting leader and warned bloodshed must be avoided.

Impeached South Korean President Yoon Suk Yeol, in a message to conservative supporters, vowed to 'fight to the end' against 'anti-state forces.'
