North Korea accuses South of sending drones over Pyongyang, Seoul denies involvement

North Korea has accused South Korea of sending unmanned drones over Pyongyang, with the drones allegedly dropping "numerous leaflets full of political propaganda and slander" according to North Korea. The North Korean Foreign Ministry has called the intrusion a "grave political and military provocation" and stated that it requires retaliatory action, warning that it could lead to armed conflict. South Korea has denied sending drones to Pyongyang, but North Korean forces have issued a warning that they will prepare "all means of attack" capable of destroying the southern side of the border if the provocations continue. The relations between the two Koreas are at one of their lowest points in years, with North Korean leader Kim Jong Un declaring South Korea as his country's "principal enemy".
