Lee Sung Joon, spokesperson of South Korea's Joint Chiefs of Staff, speaks during the briefing in Seoul, South Korea, Monday, June 10, 2024. South Korea resumed broadcasting anti-North Korean propaganda through loudspeakers in border areas Sunday in retaliation for the more than 1,000 trash- and manure-filled balloons the North had sent over the last couple of weeks. Hours later, Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, warned that the South created a “prelude to a very dangerous situation.” Lee said Monday Kim’s comments represented a heightened verbal threat from North Korea but he did not provide a specific assessment on the actions the North might take.
