The Constitutional Court is expected to decide in the coming days whether to oust Yoon Suk Yeol in a case that ignited South Korea's worst political crisis in decades and rattled markets.

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

South Korean President Yoon Suk Yeol, who lawmakers voted to impeach, was released from detention Saturday after spending nearly two months in custody under a criminal probe for his martial law declaration.
