North Korean troops have crossed the Military Demarcation Line (MDL) more than 20 times over the past month, according to South Korea's military.

The Joint Chiefs of Staff said in a statement Wednesday, "Our military is taking resolute operational action against North Korea's MDL violations in accordance with our standards and principles."

North Korean forces first crossed the MDL this year in the eastern sector in mid-August, and have since repeatedly crossed the line there, according to the JCS.

Under its rules of engagement, the South Korean military issues a warning broadcast when North Korean troops show signs of approaching the MDL, and fires warning shots and takes expulsion measures if the line is actually crossed.

The South Korean military has fired warning shots in most of the recent crossing cases, officials said. Considering that North Korea crossed the MDL a total of 17 times throughout last year, this year's tally has already surpassed that figure within a single month.

A JCS official explained the recent rise in crossings, saying, "The violations were identified as construction work proceeded in previously unworked sections this year," adding that "the crossings are not assessed to stem from any change in North Korean military activity or unusual movements."

North Korea declared the two Koreas "hostile states" and has since 2024 worked to turn the MDL into a de facto border. It has cleared vegetation, installed fences and laid mines inside the Demilitarized Zone, efforts that have reportedly gone hand in hand with intensified patrols along the MDL.

The recent violations are concentrated mainly in the eastern sector. A small group of North Korean soldiers, presumed to be a patrol unit, crosses the MDL in a specific section and then withdraws once South Korean forces fire warning shots.

In response to the rise in crossings, the South Korean military is reviewing measures to strengthen its alert posture, including moving surveillance equipment inside the DMZ further north. In addition, it has asked the UN Command to investigate whether the North's MDL violations constitute breaches of the armistice agreement. It is also holding consultations to coordinate on potential flashpoints -- such as discrepancies between the two Koreas over the MDL's exact baseline -- that could trigger military clashes.

The UN Command said, "In accordance with the armistice agreement, we continue to monitor activities inside the DMZ and are working closely with the Republic of Korea." It added that "we do not publicly comment on ongoing investigations or specific operational matters." However, it noted that it is "working to uphold and implement the armistice agreement, reduce the risk of miscalculation, and maintain peace and stability on the Korean Peninsula."
