By Joyce Lee and Ju-min Park SEOUL (Reuters) -South Korean President Yoon Suk Yeol was ousted by the Constitutional Court on Friday, which upheld parliament's impeachment motion over his short-lived imposition of martial law last year that sparked the country's worst political crisis in decades.

South Korean President Yoon Suk Yeol, who declared martial law and had special forces storm the National Assembly, is removed from office.

A large crowd of protesters erupted in cheers when the announcement came from South Korea's Constitutional Court. All eight of the judges on the court agreed that Yoon Suk-yeol had “violated the basic principles of a democratic state” and would be removed from office immediately.
