A North Korean balloon carrying waste landed on the grounds shared by the South Korean presidential office and the National Defense Ministry in central Seoul. The balloon contained mostly paper and plastic scraps, and the South Korean military confirmed that the waste did not appear to be hazardous. This incident marked the tenth time this year that North Korea had scattered trash across South Korea using balloons. The South Korean military emphasized the importance of picking up the balloons and their contents after they reach the ground to minimize damage. The Security Service, along with the Joint Chiefs of Staff, is maintaining monitoring and surveillance of the balloons possibly entering the skies over the presidential office. Some South Korean lawmakers have expressed concerns about the infiltration of the no-fly zone around the presidential office by North Korean balloons and suggested that the government could do more to dissuade activist groups from flying anti-Pyongyang leaflets over the border to placate North Korea. Former Defense Ministry spokesperson Boo Seung-chan suggested that some restraint on leaflet activism might help ease tensions between the two Koreas.
