Seoul mulls 'proportionate measure' over Pyongyang's loudspeaker threat

South Korea said on Thursday it would take a “proportionate measure” if North Korea resumes operating propaganda loudspeakers along the border, without providing details about such measures. In a wider response to the border tension that resulted from the explosion of North Korean mines, which injured South Korean soldiers, Seoul said it would send a letter to the president of the United Nations Security Council (UNSC) to explain that the mine planting was in violation of the 1953 Korean Armistice Agreement and call for U.N.-level actions. "If North Korea takes action, we believe there should be a proportionate measure," Ministry of National Defense spokesperson Chung Binna said when asked if Seoul will set up and operate its own propaganda loudspeakers. But she added nothing has been decided. The remarks came as Kim Yo-jong, the powerful sister of North Korean leader Kim Jong-un, has said in two statements since Tuesday that Pyongyang will resume propaganda loudspeaker broadcasts against South Korea, claiming that Seoul wrongfully accused North Korean troops of crossing the border.
