South Korea's Democratic Party has submitted a motion to impeach President Yoon Suk Yeol following his controversial martial law declaration. The motion requires a two-thirds majority in the National Assembly before being sent to the Constitutional Court and could see a vote by the weekend. Yoon's declaration on Tuesday restricted political activities and press freedoms. It prompted mass protests and a swift parliamentary vote demanding its repeal. Yoon withdrew troops and pledged to lift martial law pending a cabinet quorum while meeting political leaders amid rising turmoil.
