North Korea has issued a warning to South Korea, stating that its troops are ready to strike if more drones are detected crossing the border.
The threat comes after South Korea allegedly flew drones over Pyongyang, the capital of North Korea, and dropped propaganda leaflets.
North Korea claims that the drone flights occurred three times and that further incidents will be met with force.
The tense situation between the two Koreas has been escalating in recent months, with North Korea expressing growing frustration over South Korea's actions.
