North Korea accused South Korea on Friday of sending drones to scatter a "huge number" of anti-North leaflets over its capital Pyongyang, in what it called a political and military provocation that could lead to armed conflict.

North Korea says South Korea flew propaganda-dropping drones over its capital city, warning the "safety lock on our trigger has now been released" in response.

North Korea has accused rival South Korea of flying drones to its capital to drop anti-North Korean propaganda leaflets and threatened to respond with force if such flights occur again.
