President Yoon Suk Yeol plunged the East Asian democracy into chaos last week with his short-lived martial law declaration.

South Korean President Yoon Suk Yeol has been banned from leaving the country over a failed attempt at imposing martial law, amid growing calls for him to step down and a deepening leadership crisis.

Police, prosecutors and investigators have deemed President Yoon Suk Yeol as a suspect in a rare investigation into a sitting president for possible insurrection charges.
