Protesters stage a rally demanding the stop of military exercises and propaganda amid rising tensions between North and South Korea, in Seoul, South Korea, Monday, June 24, 2024. South Korea is monitoring an expected change in the wind direction on Monday that could allow North Korea to send more trash-carrying balloons across their heavily armed border, in their latest bout of tit-for-tat psychological warfare. North Korea threatened Friday to retaliate after a South Korean activists’ group sent balloons carrying anti-North Korean propaganda leaflets across the border. The signs read: "Stop artillery exercise in the West Sea" (AP Photo/Ahn Young-joon)
