The Joint Chiefs of Staff and the United Nations Command Military Armistice Commission began an investigation on September 27 near the site of a suspected mine explosion close to the Military Demarcation Line (MDL) on the Western Front. This marks six days since the incident occurred on September 21. The investigation team approached the area near the suspected explosion site but decided to conduct further investigations later due to the risks posed by additional mines and the fatigue of operational personnel.


The Joint Chiefs of Staff announced that the joint investigation by South Korean forces and the UN Command reached the vicinity of the suspected explosion site. The team consisted of over 40 members, including military personnel from South Korea, the UN Command's Military Armistice Commission Secretary, and other relevant officials, some of whom were involved in operations at the time of the incident.


Starting at 9 a.m. and continuing until sunset, the investigation team utilized mine detectors to conduct a thorough search of the routes within the Demilitarized Zone (DMZ) and secured additional pathways. However, due to the high risk of unconfirmed mine areas and extreme fatigue among operational personnel, they decided to proceed with further investigations later. The South Korean military and the UN Command plan to clarify the exact cause of the explosion and the circumstances surrounding the incident through subsequent investigations.


Previously, on September 26, the South Korean military and the UN Command conducted preliminary preparations for the first on-site investigation since the incident. They assessed the safety of the routes and checked the monitoring and communication status, evaluating the overall operational environment. About 20 personnel were involved in that operation.


As the military accelerates its efforts to determine the cause of the incident, political circles have raised suspicions regarding the timing of the investigation's commencement. Independent lawmaker Han Dong-hoon staged one-person protests in front of the Defense Ministry on September 24 and 26, urging immediate on-site investigations. He stated, "If the investigation is delayed and evidence is lost, it will be impossible to determine the cause. The Yoon Suk Yeol administration and the Defense Ministry are responding slowly out of fear of Kim Jong Un's regime. I will hold them accountable for the delay in the investigation alongside the public."


On the same day, People Power Party leader Jang Dong-hyuk claimed during a press conference at the National Assembly that the exploded mine is likely a wooden box mine planted by North Korean forces across the MDL. He criticized the military for only beginning preliminary preparations five days after the incident, asserting, "If President Yoon intentionally delayed the investigation, it would be a clear act of treason, warranting impeachment and immediate arrest for trial."


Additionally, the Citizens' Livelihood Countermeasure Committee filed a complaint with the Seoul Metropolitan Police Agency against nine individuals, including President Yoon, National Security Office Director Wi Sung-lak, former Defense Minister Ahn Gyu-baek, and current Defense Minister Kang Shin-cheol, for abuse of power, neglect of duty, and general treason. The complaint also includes Joint Chiefs of Staff Chairman Jin Young-seung, Army Chief of Staff Kim Kyu-ha, Ground Operations Commander Lee Sang-ryeol, acting 1st Corps Commander Kang Kwan-beom, and 25th Division Commander Choi Seok-yoon.


As the mine explosion incident escalates into a legal dispute, the key to future investigations will be how much evidence can be secured to clarify the cause and circumstances of the explosion. Furthermore, to dispel allegations of intentional delays in the investigation, explanations regarding the preparation process and safety constraints prior to the investigation's commencement will also be necessary.


Meanwhile, on the last day of the Chuseok holiday, Defense Minister Kang was reported to have arrived at the Defense Ministry to receive briefings related to the investigation of the suspected mine explosion incident. The Defense Ministry plans to announce initial investigation results this month, reflecting public calls for a swift inquiry, ahead of comprehensive analysis results.
