South Korea warned North Korea on Sunday that it will see "the end of its regime" if it causes any harm to its people, after the North threatened a "horrible disaster" over the alleged flight of drones over its capital.

North Korea accused South Korea of flying propaganda-filled drones over Pyongyang and threatened “retaliation,” state media reported Friday.

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.
