SEOUL, Oct. 5 (Yonhap) -- North Korea-planted land mines exploded and injured three South Korean soldiers inside the Demilitarized Zone (DMZ) last month, South Korea's military concluded Monday, saying it conducted a mine-clearing operation at the blast site in response.

The South's military announced the final result of its joint investigation with the U.N. Command (UNC) into the Sept. 21 mine blast, confirming its preliminary findings that resin antipersonnel mines deliberately planted by Pyongyang south of the Military Demarcation Line (MDL) were the cause of the blast.

Two South Korean troops suffered critical injuries to their ankles, while a third sustained minor injuries.

The mines involved in the recent blasts contained trinitrotoluene (TNT) and thermosetting resin components consistent with North Korean mines, Lt. Gen. Kwon Dae-won, vice chairman of the South's Joint Chiefs of Staff (JCS), said in a press briefing.

Fragments recovered from the injured soldiers were identical to the North Korean plastic antipersonnel mines previously recovered from the Imjin River -- featuring a brown casing with a lattice pattern on the cover, he said.

North Korean mines are often found south of the MDL after they are swept away to south of the inter-Korean border in floods, but the ones that triggered the recent blast were "buried about 3 to 10 centimeters underground," Kwon said, citing the joint investigation result.

"The UNC has also found that those mines were intentionally placed, and it estimated the installation occurred roughly 12 months prior," he said.

The military said GPS measurements showed that the two blast sites and the site where an additional mine was discovered were all located about 10 meters south of the MDL.

The JCS said it removed the minefield south of the MDL at around 12:51 p.m. Monday, in its first operation in response to the mine blast.

The military released footage of the operation showing black smoke billowing and the booming sound of an explosion, describing the mission as an "effective" operation on the North's mine-laying sites verified by the UNC.

The military vowed to continue mine-removal operations in the area if North Korea refuses to voluntarily remove its mines planted there.

"The military strongly calls on North Korea to offer a sincere apology to the South Korean soldiers injured in the mine blast and immediately remove the mines it planted in violation of the Armistice Agreement," Kwon said.

The Armistice Agreement, which ended the 1950-53 Korean War, prohibits hostile acts "within, from or against" the DMZ, the buffer zone covering the MDL. It also bans border crossings unless authorized by the Military Armistice Commission.

North Korea has been fortifying the inter-Korean border since April 2024 by reinforcing barbed-wire fences, planting mines and erecting anti-tank barriers along the MDL after its leader Kim Jong-un declared inter-Korean ties to be those between "two states hostile to each other" the previous year.

The JCS said it has detected increasing North Korean activity along the MDL since March 2025, estimating that as many as 7,000 troops may have been mobilized daily to clear land for mine-laying and fencing, especially along the eastern front.

Since the North began fortifying the border, its border intrusions to south of the MDL have spiked to more than 50 cases this year, from nine in 2024 and 17 in 2025, the JCS said.

North Korea has denied responsibility for the recent explosions inside the DMZ.

Kim Yo-jong, the powerful sister of leader Kim, has dismissed Seoul's findings as a fabrication and warned of retaliation if South Korea takes corresponding action.

首尔，10月5日（韩联社）——韩国军方周一表示，上个月朝鲜埋设的地雷在非军事区（DMZ）爆炸，造成三名韩国士兵受伤。军方已在爆炸现场进行了排雷行动作为回应。

韩国军方公布了与联合国军司令部 (UNC) 对 9 月 21 日地雷爆炸事件的联合调查最终结果，证实了其初步调查结果，即平壤故意埋设在军事分界线 (MDL) 以南的树脂杀伤人员地雷是造成爆炸的原因。

两名韩国士兵脚踝严重受伤，另有一名士兵受轻伤。

韩国联合参谋本部副委员长权大元中将在新闻发布会上表示，最近爆炸中涉及的地雷含有三硝基甲苯（TNT）和热固性树脂成分，与朝鲜地雷一致。

他说，从受伤士兵身上找到的碎片与之前在临津江中发现的朝鲜塑料杀伤人员地雷完全相同——外壳呈棕色，盖子上有网格图案。

权先生援引联合调查结果称，朝鲜地雷经常在洪水冲到朝韩边界以南后，在军事分界线以南被发现，但引发最近爆炸的地雷“埋在地下约 3 至 10 厘米处”。

“北卡罗来纳大学也发现这些地雷是故意放置的，据估计，安装时间大约在 12 个月前，”他说。

军方表示，GPS测量结果显示，两个爆炸地点和发现另一枚地雷的地点都位于MDL以南约10米处。

联合参谋部表示，周一下午 12 点 51 分左右，他们清除了 MDL 南部的雷区，这是他们针对地雷爆炸事件采取的首次行动。

军方公布了行动的视频，视频显示黑烟滚滚，爆炸声震耳欲聋。军方称此次行动是针对北方布雷点的一次“有效”行动，并已得到联合国军的证实。

如果朝鲜拒绝自愿清除埋设在该地区的水雷，军方誓言将继续在该地区开展排雷行动。

权表示：“军方强烈呼吁朝鲜向在爆炸中受伤的韩国士兵真诚道歉，并立即清除其违反停战协定埋设的地雷。”

结束1950-53年朝鲜战争的《停战协定》禁止在非军事区（涵盖军事分界线的缓冲区）内、从非军事区出发或针对非军事区采取敌对行动。该协定还禁止未经军事停战委员会授权的越境行为。

自2024年4月以来，朝鲜一直在加强朝韩边界的防御，包括加固铁丝网、埋设地雷以及沿军事分界线设置反坦克障碍。此前一年，朝鲜领导人金正恩宣布朝韩关系是“两个相互敌对的国家”之间的关系。

联合参谋本部表示，自 2025 年 3 月以来，已发现朝鲜在军事分界线沿线的活动日益频繁，估计每天可能有多达 7000 名士兵被动员起来，清理土地以便布雷和修建围栏，尤其是在东部战线。

联合参谋本部表示，自朝鲜开始加强边境防御以来，其越过军事分界线以南的边境入侵事件已激增至今年的 50 多起，而 2024 年为 9 起，2025 年为 17 起。

朝鲜否认对近期非军事区内的爆炸事件负责。

金正恩的妹妹、权势滔天的金与正驳斥了首尔方面的调查结果，称其为捏造，并警告说，如果韩国采取相应行动，将进行报复。
