South Korea’s military fired warning shots last week after multiple North Korean soldiers briefly crossed the Military Demarcation Line in the eastern section of the Demilitarized Zone, prompting them to return to the North, Yonhap News Agency reported Sunday, citing an unnamed government source.
The incident marked the first reported violation of the Military Demarcation Line, or MDL, by North Korean troops this year and the first time South Korea fired warning shots in response to such a crossing in 2026.
The soldiers were believed to have been patrolling the area when they crossed the boundary, Yonhap reported. They returned to the North Korean side after the warning shots, and no further unusual activity was reported.
Under South Korea’s rules of engagement, the military broadcasts warnings when North Korean troops approach the MDL and fires warning shots if they cross the boundary.
The MDL runs through the Demilitarized Zone separating North and South Korea and remains a legacy of the 1950-53 Korean War.
The conflict ended with an armistice rather than a peace treaty, meaning the two Koreas remain technically at war.
Brief crossings of the MDL by North Korean soldiers have been reported repeatedly in recent years as Pyongyang has strengthened fortifications on its side of the border.
The activity followed North Korean leader Kim Jong-un’s declaration in late 2023 that inter-Korean relations were between “two hostile” states.
North Korean troops violated the MDL 17 times last year, according to Yonhap.
