Trash from a North Korean balloon has fallen on the South Korean presidential compound in Seoul for the second time, raising security concerns. No dangerous items were found in the waste. This incident follows increased tensions between North and South Korea, with North Korea accusing the South of drone activities. North Korea has been sending balloons with propaganda leaflets and waste into South Korean airspace. The South Korean military has warned North Korea against these actions, while experts doubt the accuracy of the balloon drops. The situation is further complicated by North Korea's military cooperation with Russia.
