Candle-lit vigils and rallies were held across South Korea on Wednesday, a nation outraged and frustrated by the president’s surprise declaration of martial law the night before called for his resignation.

South Korea’s president Yoon Suk Yeol declared martial law, asking the armed forces to suspend normal democratic freedoms, for example being able to protest. Yoon said martial law was needed because of threats from North Korea. But critics say Yoon wanted to use martial law as a response to scandals and problems he faces.
