South Korean President Yoon Suk Yeol reversed his declaration of martial law on Wednesday after parliament unanimously voted against it, sparking public protests and political turmoil.

Yoon had declared martial law Tuesday night, citing threats from "anti-state forces" among political opponents. However, lawmakers from all parties, including his own, condemned the move. South Korean law requires martial law to be lifted if rejected by a parliamentary majority.

Protesters outside parliament celebrated the reversal, chanting, "We won!" Meanwhile, opposition leaders called for Yoon's resignation or impeachment, accusing him of treason.

The White House welcomed Yoon’s decision, expressing relief over the de-escalation. The crisis had raised international alarm, with U.S. officials closely monitoring the situation in the key ally nation.

Yoon’s declaration marked the first martial law in South Korea since 1980 and further damaged his approval ratings, which have been near 20%. Analysts warn the crisis could lead to snap elections, increasing political uncertainty in the region.
