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.

South Korea’s Constitutional Court is set to rule Friday on the impeachment of President Yoon Suk Yeol, either removing him from office or restoring his powers four months after he threw the country into turmoil with an ill-fated declaration of martial law.
