South Korean President Yoon Suk Yeol declared an 'emergency martial law,' Tuesday accusing the country's opposition of controlling the parliament, sympathizing with North Korea and paralyzing the government with anti-state activities. Yoon made the announcement in a televised briefing Tuesday, vowing to 'eradicate pro-North Korean forces and protect the constitutional democratic order.' It wasn't immediately clear how Yoon's step would affect the country's governance and democracy. "Through this martial law, I will rebuild and protect the free Republic of Korea, which is falling into the depths of national ruin," Yoon said during a televised speech, invoking South Korea's formal name.
