“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.”
