Kim Yo Jong, North Korea’s top foreign policy official, slammed Seoul's accusations over the September 21 DMZ blasts that injured three soldiers.
The explosions occurred roughly 10 metres south of the demarcation line as troops cleared a rarely accessed, vegetated patrol route. The DMZ stretches 248 kilometres, 4 kilometres wide, and is believed to contain around two million land mines.
Kim Yo Jong called the South Korean claims a "conspiratorial farce" and accused Seoul of making "groundless claims" to justify a pretext for military provocation.
The incident follows a 2015 blast that wounded two soldiers and sparked a surge of tensions, weapons demonstrations, and propaganda broadcasts before diplomatic talks eased the crisis.
South Korean Joint Chiefs announced a preliminary assessment that North Korean mines were likely responsible after a joint inspection with the US‑led United Nations Command, and they will maintain heightened readiness while planning further inspections. The injured troops were subsequently transported to military hospitals for treatment.
