South Korean President Yoon Suk Yeol declared martial law on Tuesday evening, aiming to eliminate "anti-state" forces and combat alleged opposition sympathies with North Korea.
Hours later, South Korea's parliament voted unanimously to lift the martial law, with the National Assembly Speaker calling for the withdrawal of police and military forces.
President Yoon's declaration sparked immediate criticism, with opposition leaders and even members of his own party calling it a return to authoritarianism and an unconstitutional act.
Following the declaration, the military suspended political gatherings and demanded striking doctors return to work, threatening arrests for violations.
This was the first martial law declaration since South Korea's democratization in 1987, marking a sharp escalation in tensions between the president and the opposition-controlled parliament.
