Three South Korean soldiers injured in landmine border explosion

Three South Korean military officers sustained injuries in an explosion that occurred during an operation near the heavily fortified Demilitarized Zone (DMZ) with North Korea, according to Seoul’s Joint Chiefs of Staff (JCS). The incident took place south of the Military Demarcation Line (MDL) within the DMZ, one of the world’s most heavily mined borders.

The injured officers were evacuated via helicopter, with one undergoing further transport by road before being airlifted to a medical facility. The cause of the explosion remains unknown, as it is unclear whether it was triggered by a North Korean mine, a South Korean mine, or another type of explosive device. The military has not disclosed the extent of the officers' injuries.

The DMZ, spanning 248 kilometers and approximately 4 kilometers in width, has divided the Korean Peninsula since the 1953 armistice that ended the Korean War. Despite its official status as a demilitarized zone, the northern and southern boundaries of the DMZ are among the most heavily fortified areas globally, strewn with landmines.

An estimated 800,000 mines, many dating back to the Korean War, are believed to be buried in the region, with additional mines being laid by North Korea in recent years. In 2024, following North Korean leader Kim Jong Un's designation of South Korea as its "principal enemy," North Korea intensified its military activities by laying mines and constructing anti-tank barriers along the border to consolidate its territorial claims.

South Korea's military has previously reported incidents where North Korean soldiers were killed or injured in accidental mine explosions during such operations. Landmine incidents have historically exacerbated tensions between the two Koreas. In 2015, two South Korean soldiers were seriously wounded, with one losing both legs, after a landmine detonated on the southern side of the DMZ, prompting Seoul to attribute the act to North Korean troops who allegedly crossed the MDL to plant the mines—a claim Pyongyang firmly denied.

The latest explosion occurred amid President Lee Jae Myung's ongoing calls for unconditional dialogue with North Korea, a demand that has thus far gone unaddressed by Pyongyang.
