South Korea Accuses North Korea of Planting DMZ Mines that Injured Soldiers

On September 21, two explosions on the western front of the Demilitarized Zone (DMZ) wounded South Korean soldiers. South Korean sources report three soldiers injured; one source cites two. Joint investigations by the South Korean Joint Chiefs of Staff (JCS) and the U.S.-led United Nations Command (UNC) concluded the blasts were caused by plastic anti-personnel mines deliberately buried south of the Military Demarcation Line (MDL).

Since April 2024, North Korea has intensified “border fortification” work, deploying thousands of workers to install mines, fences and anti-tank barriers. The DMZ, a 4-km-wide buffer, already contains an estimated two million land mines.

The incident is viewed as a violation of the Armistice Agreement, raising the risk of escalation along one of the world’s most fortified borders. It coincided with a North Korean ballistic missile launch the day after Seoul’s demand for an apology, underscoring heightened regional tension.
