A possible unmanned aerial vehicle (UAV) circled South Korean skies near the inter-Korean border on Tuesday afternoon, footage recorded by NK News shows, raising questions about the frequency and origin of flights in the sensitive area weeks after a high-profile North Korean drone intrusion.

Under the 2018 Comprehensive Military Agreement between the two Koreas, flying UAVs is prohibited within 6 miles (10 km) of the military demarcation line (MDL) along the western border —  except for emergency and agricultural reasons and only after giving prior notification. ROK law also bans civilians from flying drones unless they receive prior government approval.
