SEOUL: Impeached South Korean President Yoon Suk Yeol arrived at court for the first time Saturday to attend a hearing that will decide whether to extend his detention as investigators probe his failed martial law bid. Yoon, who has claimed his arrest is illegal, threw the nation into chaos on December 3 when he attempted to suspend civilian rule, citing the need to combat threats from “anti-state elements.” Yoon’s die-hard supporters gathered outside the court building Saturday, even trying to surround the blue van carrying the suspended leader.
