@bbcnews: Protesters gathered outside South Korea's parliament in Seoul, after President Yoon Suk Yeol declared emergency martial law. In a surprise TV address on Tuesday night, he said rule by the military was necessary to protect the country from North Korea's communist forces and to eliminate anti-state elements. Lawmakers have since voted to block the president's move, after both the ruling party and opposition vowed to obstruct the declaration. But the South Korean military has said it will maintain martial law until it is lifted by President Yoon Suk Yeol, according to the country's national broadcaster. #SouthKorea #yoonsukyeol #martiallaw #Parliament #Politics #Seoul #protest #Protesters #BBCNews
