North Korea has sent approximately 500 balloons filled with trash into South Korea's airspace over the past 24 hours, South Korean officials reported on Thursday (Jul 25). These balloons have disrupted flights and even ignited a fire on a residential building's roof. This act is part of an ongoing propaganda campaign by Pyongyang against North Korean defectors and activists in the South, who often send balloons carrying anti-Pyongyang leaflets, medicine, money, and USB sticks loaded with K-pop videos and dramas. A suspected balloon led to a two-hour suspension of take-offs and landings at Seoul's Gimpo Airport on Wednesday evening, according to an official at the Korea Airports Corporation. Similar disruptions have occurred at Incheon International Airport in recent weeks. In Gyeonggi province, near Seoul, a balloon caused a fire on a residential building, which firefighters quickly extinguished. South Korea's military reported that some trash balloons were equipped with timed poppers designed to spread trash and potentially cause fires. Lee Sung-jun, a spokesperson for South Korea's Joint Chiefs of Staff, confirmed that 480 balloons had landed, mostly carrying paper and plastic trash. Some balloons even landed near the heavily guarded presidential office in Seoul on Wednesday.
