A possible mine explosion in the Demilitarized Zone (DMZ), the heavily fortified border separating North and South Korea, has injured three people, including at least one South Korean soldier. The incident was reported by South Korean television channel Yonhap TV on Monday, September 21. According to a military official, the soldier was seriously hurt during an operation involving the 25th Infantry Division. It remains unclear whether the mine was placed by North Korean or South Korean forces. The DMZ is a 4-kilometer-wide buffer zone stretching nearly 250 kilometers along the Korean Peninsula. It was established after the Korean War (1950–1953) to prevent further conflict and is considered one of the most heavily mined areas in the world. Experts estimate that more than 800,000 landmines are still buried in the region, many dating back to the war, while others were laid in the decades that followed or even more recently to prevent enemy infiltration. Tensions between the two Koreas have remained high in recent years. North Korean leader Kim Jong Un officially abandoned the idea of reunification with the South at the end of 2023, leading to increased military activity on both sides. In response, North Korea has reportedly placed new mines and constructed additional fortifications along the border, making it even more difficult to cross. The recent incident highlights the ongoing dangers posed by the DMZ, where both military and civilian personnel face risks from unexploded ordnance. Despite numerous efforts to clear the area, the presence of so many mines continues to pose a significant threat to safety and stability in the region.
