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 main opposition party urged President Yoon Suk Yeol to resign immediately or face impeachment, hours after Yoon ended short-lived martial law.

South Korean President Yoon Suk Yeol shocked the nation in a televised address, declaring martial law and calling in troops to secure the National Assembly building where parliament sits.
