An investigation into the suspected landmine explosion that occurred on the Western Front DMZ on the 21st was conducted by our military and the UN Command on the 27th. However, due to the risk of unidentified mine areas and the fatigue of the operational personnel, the actual blast site could not be reached, and further investigation was promised. The investigation team secured access routes and conducted precise mine searches. They plan to release objective facts to the public through additional investigations to determine the cause of the accident.
