South Korea’s ruling party has thrown its support behind attempts to impeach embattled President Yoon Suk Yeol over his ill-fated decision to declare martial law that sparked a political crisis and widespread public anger in the country.

South Korea’s President Yoon Suk Yeol accused the opposition of trying to paralyze his administration and siding with North Korea in a defiant speech Thursday as the chief of his own party called for his impeachment.

South Korea's police chief became the latest top official to be arrested, Yonhap news agency said on Wednesday, in a widening investigation into President Yoon Suk Yeol's failed martial law that has plunged the country into a constitutional crisis.
