South Korean President Yoon Suk Yeol's security chief said on Friday the impeached leader has been unfairly treated.

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.

A South Korean court issued warrants Tuesday to detain impeached President Yoon Suk Yeol and search his office and residence over his short-lived declaration of martial law.
