South Koreans gathered in huge numbers in the capital Seoul on Saturday to support or oppose impeached president Yoon Suk Yeol before a court decides whether his short-lived declaration of martial law disqualifies him from office.

Thousands of South Koreans have filled the streets of downtown Seoul in massive rival rallies for and against impeached President Yoon Suk Yeol.

South Korea's Constitutional Court could soon rule whether to dismiss or reinstate impeached conservative President Yoon Suk Yeol.

South Korea's acting President Choi Sang-mok called on Friday for the nation to respect and accept any decision, ahead of a Constitutional Court's ruling on the impeachment of leader Yoon Suk Yeol over his short-lived martial law order.

Amid rival mass rallies in Seoul, Yoon Suk Yeol is freed from detention as he faces trial on insurrection charges over his short-lived imposition of martial law.

The move followed a court ruling that the detention of President Yoon Suk Yeol was invalid, but it won’t affect the insurrection and other charges he faces for declaring martial law.

South Korea’s impeached president, Yoon Suk Yeol, on Saturday was released from jail, where he was being held while he faces a criminal trial on charges of insurrection for declaring martial law in December.

Tensions are mounting across South Korea ahead of a ruling expected next week on the fate of impeached President Yoon Suk Yeol.

Thousands of people are rallying across South Korea, supporting suspended President Yun Suk-yeol ahead of a Constitutional Court verdict. The court ruling, expected later this month, will decide if South Korea will uphold Yun's impeachment over his declaration of martial law.
