South Korean President Yoon Suk-yeol declared martial law on December 3, citing threats from North Korean forces and challenges from the opposition over a budget proposal. However, less than three hours later, the majority of lawmakers voted against it, effectively overturning the measure. The declaration led to public protests, with hundreds gathering in front of the National Assembly. International responses include concerns from the U.S. and Britain regarding the implications for the rule of law in South Korea.
