In declaring martial law early last month, Yoon used similar language, citing the need to “eradicate pro-North Korean forces.” He later defended the move as a temporary measure to warn his opposition rivals, whom he accused of obstructing governance. Critics, however, viewed the declaration as an authoritarian overreach.

South Korea's Presidential Security Service chief resigned Friday and acting President Choi Sang-mok accepted it. President Yoon Suk Yeol remains in his fortified residence as law enforcement seeks to arrest him.

The president's ultraconservative supporters believe that the country has been overrun by North Korea sympathizers conspiring to destroy South Korea's freedoms.
