SEOUL -- South Korean demonstrators marched towards the presidential office in the capital city of Seoul on Wednesday night as the political crisis ignited by President Yoon Suk-yeol's sudden declaration of martial law in the country dragged on.

The demonstrators were seen chanting slogans "Arrest Yoon Suk-yeol" and "Yoon must step down".

The march took place after the demonstrators staged a candlelight rally near Gwanghwamun in central Seoul, demanding that Yoon step down.

The organizers estimated that 10,000 people participated in the mass event, while the turnout figure given by the local police was around 2,000.

Yoon declared an emergency martial law late Tuesday and lifted the short-lived decree in the early hours of Wednesday following a vote by lawmakers at the National Assembly to reject it.
