• South Korea suspects that North Korean mines caused recent explosions in the DMZ.
• The blasts injured three South Korean personnel and are deemed a violation of the armistice.
• The investigation indicates that mines may have been recently planted by North Korean forces.
• Military officials suggest that detection efforts were hampered by dense vegetation in the area.
• Relations between North and South Korea continue to worsen amid ongoing tensions.

South Korea's military has indicated that the injuries sustained by three officers in the Demilitarized Zone (DMZ) on September 21 were likely due to explosions from North Korean mines. A preliminary investigation, which included the United Nations Command, suggested that one of the blasts was near areas observed to have changes in terrain indicative of recent North Korean activity, including mine laying. "Taking into account the crater and the pattern of the flames from the explosion, the extent of the injuries sustained by the service members...we assess that North Korean landmines are highly suspected to have caused the blast," stated Army Lieutenant-General Kwon Dae-won from the Joint Chiefs of Staff, underscoring the rising tensions as both sides remain technically at war, according to India Times and Al Jazeera.

On September 29, officials confirmed that the explosions, which severely injured one soldier leading to a foot amputation, were a direct violation of the armistice agreement in place since the Korean War. Defence Minister Kang Shin-chul emphasized that North Korea would bear responsibility for these incidents, prompting South Korea to consider appropriate military responses. This tension is further exacerbated by the fact that landmines remain a persistent hazard within the heavily fortified DMZ, with an estimated 2 million mines laid in the region. Kang highlighted the difficulty in detecting these mines due to dense vegetation, hindering timely military assessments, according to Channel News Asia.

Military analysts noted that the area where the incident occurred has seen increased activity from North Korean forces, which have been reportedly fortifying their positions along the frontier, including laying additional mines since 2024, further complicating the security dynamic in the region. "Our current assessment is that the mines may not have been detected because the detectors were being operated too far above the ground," stated Minister Kang, emphasizing that the military would utilize a range of measures in response to the revelations stemming from the investigation, according to Al Jazeera and Channel News Asia.
