Pyongyang acted after South Korea, responding to the recent North Korean satellite launch, cancelled elements of the 2018 Comprehensive Military Agreement.
“The 2018 agreement laid down a number of measures that would lower military tensions and accidental military clashes between the two sides. Among them included the dismantling of guard posts along the Demilitarized Zone, a no-fly zone along the DMZ, the cessation of live fire artillery drills and field exercises above the regiment level and above within three miles of the Military Demarcation Line, with a similar ban on live fire and maritime maneuvers exercise along the maritime borders in the East and West Sea and a ban tactical live-fire drills involving fixed-wing aircraft, including the firing of air-to-ground guided weapons within the designated no-fly zones in the eastern and western regions of the MDL,” reports USNI.
