North Korea said Friday that South Korea has sent unmanned drones over Pyongyang three times since last week, calling the move a military provocation and a violation of its sovereignty.In a message delivered through the Korean Central News Agency, the North's foreign ministry claimed South Korea sent unmanned drones carrying leaflets over Pyongyang on Oct. 3, as well as on Wednesday and Thursday this week."(The move) is a blatant infringement of the sacred national sovereignty and safety, and a violent violation of international law," the North's ministry said, calling for South Korea to immediately end its "dangerous provocation" that could lead to "an armed conflict that could even escalate into war."This image, released by North Korea's official Korean Central News Agency on Oct. 11, 2024, shows a purported drone (in large circle) and a pack of leaflets (in small circle) that Pyongyang claims were sent by South Korea.
