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 was banned from leaving the country Monday as investigations for treason and abuse of power over his short-lived martial law decree get underway.

Under Korean law, a president is immune from prosecution on all matters except leading an insurrection or acts of treason, which Yoon Suk Yeol has been accused of after his martial law attempt.
