North Korea Rejects Seoul's Finding on the DMZ Mine Blast and Warns of Immediate Retaliation

Kim Yo Jong, the sister of North Korean leader Kim Jong Un and a senior official in her own right, denied that North Korea was responsible for explosions inside the Demilitarized Zone and accused Seoul of fabricating the finding. Deutsche Welle reported her statement accusing the South of a conspiracy after the South Korean military attributed the blast to the North.

The incident occurred on September 21, when two explosions severely injured three South Korean soldiers, one of whom lost a foot. South Korea's Defence Ministry concluded after an investigation that North Korean mines were highly suspected, and that the devices were probably laid during Pyongyang's border fortification work.

That finding has since been corroborated by a body distinct from South Korea's own chain of command. The United Nations Command, which oversees the armistice mechanism and includes personnel from multiple troop-contributing nations, conducted a joint on-site investigation with the South Korean military and reported finding an active North Korean anti-personnel mine on the South Korean side of the Military Demarcation Line. Both the Command and South Korea's Joint Chiefs of Staff declared the placement of the mine a violation of the 1953 Armistice Agreement, and South Korea's military formally demanded an apology from North Korea and called for an immediate halt to the border fortification work it blames for the blast.

Kim's statement, issued under the title about those behind the provocation paying a price for their self-staged farce, compared the case to the wooden-box landmine incident of a decade ago and said the South was cooking up groundless results for political purposes, rejecting the findings of both South Korea's own investigation and the multinational Command. She also set a tripwire: if South Korean troops move beyond warning shots and fire on North Korean soldiers, Kim said, the North will retaliate immediately. Seoul has not said it intends to respond with force, and the two governments now hold incompatible accounts of the same event, though one side's version now carries the additional weight of an international command's independent confirmation.

The fortification work at the centre of the dispute is itself a structural change. Pyongyang has been physically sealing the inter-Korean border, which puts mine-laying crews and South Korean patrols in close proximity along a line where the two governments, and now a third multinational party, disagree over what happened and who is responsible.
