ROK JCS Issues Statement on DMZ Mine Provocation: "Clear Violation of Armistice Agreement; Calls on North Korea to Apologize"

[Financial News] After South Korean military authorities designated the mine explosion on a DMZ search route as an intentional provocation by North Korea, the ROK JCS issued an official statement characterizing it as a clear violation of the Armistice Agreement and demanding an official apology and responsible measures from North Korea. Following the previous day's forensic examination, which detected large quantities of explosive compounds used in North Korean lethal weapons, the military leadership issued a statement making clear that North Korea bears full responsibility for the heightened tensions around the Military Demarcation Line (MDL).
Kang Hyunwoo, Chief of Operations, ROK JCS, issued an official statement on the 30th, saying, "Despite our government's consistent efforts to promote peaceful coexistence on the Korean Peninsula, North Korea has continued to pursue so-called 'fortification of the border,' including the laying of mines near the Military Demarcation Line." He added, "This is causing tensions to rise in the border areas between the two Koreas."
The ROK JCS officially characterized the mine-laying as "a clear violation of the Armistice Agreement that undermines the spirit of existing inter-Korean agreements and must be halted immediately." It also stated, "On September 21, South Korean servicemembers conducting a routine search operation south of the Military Demarcation Line suffered serious injuries after stepping on a mine laid by North Korean forces," strongly condemning North Korea's military provocation.
Accordingly, the South Korean military called on North Korea to immediately halt activities that heighten tensions on the Korean Peninsula, including the so-called 'fortification of the border,' while strongly demanding an official apology and responsible measures for the provocation. The ROK JCS warned, "We make clear that North Korea will bear full responsibility for any situations that arise in the future."
The ROK JCS's shift to a hard-line stance was based on conclusive physical evidence from the joint on-site investigation and forensic examination completed the previous day by military authorities and the United Nations Command (UNC). The previous day, military authorities recovered one additional plastic anti-personnel mine from the accident site under the jurisdiction of the 25th Infantry Division (Republic of Korea), confirming that four North Korean mines had been planted in total. Given that the mines appeared to have been buried close together in a narrow area, the possibility that they had been naturally washed away by river flooding or other causes was ruled out.
In particular, an urgent analysis of residues from protective equipment, including the ballistic helmets and mine overboots worn by the injured servicemembers, detected Trinitrotoluene (TNT) and RDX—military-grade, high-performance explosive materials not found in the composition of South Korean mines. This scientifically established that the North Korean military had covertly crossed the MDL and planted the mines as lethal weapons.
Based on the final investigation results, the South Korean military plans to implement corresponding measures against North Korea in stages. Since the ROK JCS issued its statement, it has maintained border-wide surveillance and fire-response readiness at the highest level.
Meanwhile, the UNC, which oversees management of the DMZ and compliance with the Armistice Agreement, also officially condemned North Korea's provocation based on the results of a joint on-site investigation with the South Korean military.
In an official statement, the UNC Public Affairs Office said, "The United Nations Command, in coordination with the South Korean military, conducted a joint on-site investigation into the mine explosion that occurred in the Korean Demilitarized Zone (DMZ) on September 21." It added, "During the investigation, one North Korean anti-personnel mine was discovered in the South Korean-controlled area south of the Military Demarcation Line (MDL)."
The UNC continued, "Based on the findings of the investigation, the United Nations Command determined that a violation of the Armistice Agreement had occurred and is taking action under the established Armistice framework." It also emphasized, "The United Nations Command will remain fully committed to maintaining and implementing the Armistice Agreement, as well as fulfilling its responsibilities to preserve stability on the Korean Peninsula and prevent a rise in tensions."
-Full text of the ROK JCS statement-
Despite our government's consistent efforts to promote peaceful coexistence on the Korean Peninsula, North Korea has continued to pursue so-called 'fortification of the border,' including the laying of mines near the Military Demarcation Line, causing tensions to rise in the border areas between the two Koreas. 
This is a clear violation of the Armistice Agreement that undermines the spirit of existing inter-Korean agreements and must be halted immediately.  
In particular, on September 21, South Korean servicemembers conducting a routine search operation south of the Military Demarcation Line suffered serious injuries after stepping on a mine laid by North Korean forces. 
North Korea must immediately halt activities that heighten tensions on the Korean Peninsula, including the so-called 'fortification of the border.' We strongly demand an apology from North Korea and responsible measures. 
We make clear that North Korea will bear full responsibility for any situations that arise in the future.
