This would be the next logical step in escalation from North Korea. With that said they have already flown drones multiple times over South Korea in the past showing how hypocritical their claims against the ROK now are:
Inter-Korean tensions are escalating over propaganda leaflets, as North Korea threatened, Monday, to deploy unmanned aerial vehicles (UAVs) to drop leaflets over Seoul. The North also reiterated its claim that the South Korean military recently sent leaflet-distributing drones into its territory.
“It would be interesting to see how they will bark if a drone appears in Seoul and scatters leaflets,” Kim Yo-jong, the powerful sister of North Korean leader Kim Jong-un, said in a statement via the North’s mouthpiece Korean Central News Agency (KCNA).
Noting a hypothetical situation, she said, “An unidentified drone appears over Seoul and scatters leaflets denouncing ‘the puppet Yoon,’” apparently referring to President Yoon Suk Yeol. “Our military, individual organizations, or any individual have not flown any drones, cannot confirm such actions, and do not consider it worth responding to.”
Her remarks appear to sarcastically criticize the South Korean military’s response to North Korea’s claims that the South sent a drone carrying anti-regime leaflets over Pyongyang earlier this month and that they found debris from a UAV of the same type operated by the South Korea’s military. In response to these claims, the Joint Chiefs of Staff (JCS) said, “We cannot verify (the claim), and the claim is not worth replying.”
