North Korea accuses South Korea of sending small drones into Pyongyang carrying anti–Kim Jong Un leaflets. North Korea claims drones fly on three nights and drop propaganda near sensitive areas. North Korea calls it a grave provocation and signals possible military response. South Korea’s military denies involvement and says it cannot confirm any flights. The accusation emerges after earlier cross-border drone tensions and fuels fresh escalation fears. Military units on both sides increase alert levels.
