evidence: - First, both sides agreed to cease military exercises along the Military Demarcation Line from 01 November 2018. Specifically all live-fire artillery drills and field training exercises at the regiment level and above will be ceased, within five kilometers of the MDL. Both sides also agreed to designate No Fly Zones for all aircraft above the MDL area, from November 1st. [...] The military demarcation line (MDL) of separation between the belligerent sides at the close of the Korean war forms North Korea's boundary with South Korea. A demilitarized zone (DMZ) extends for 2,000 meters (just over 1 mile) on either side of the MDL. Both the North and South Korean Governments hold that the MDL as only a temporary administrative line, not a permanent border. The Korean Demilitarized Zone (DMZ) is an area of land encompassing 4 kilometers-wide strip of land straddling the 151 mile long Military Demarcation Line (MDL). The 27 July 1953 Armistice Agreement established the DMZ along the approximate line of ground contact between the opposing forces at the time the truce ended the Korean War.
