South Korea's military reported that its soldiers issued warnings and fired warning shots after approximately ten North Korean soldiers crossed the military demarcation line (MDL) within the demilitarized zone (DMZ). The incident occurred around 5:00 PM local time in the eastern area of the DMZ.

The Joint Chiefs of Staff stated they are closely monitoring the North Korean military's activities. No injuries were reported, and the North Korean soldiers retreated back to their side of the border following the warning shots.

A similar event took place in June 2024, shortly before Russian President Vladimir Putin's visit to Pyongyang. In that instance, the South Korean Joint Chiefs of Staff indicated the North Korean soldiers were carrying work tools. A larger group, estimated at 20 to 30 individuals, was involved in that earlier incident.

Following the June 2024 incident, Putin and North Korean leader Kim Jong Un signed a significant defensive pact. The agreement stipulates that if one side faces war due to armed invasion, the other will provide military and other assistance, utilizing all available resources.

In October 2024, the Pentagon confirmed that North Korea had deployed troops to Russia amidst the ongoing conflict with Ukraine. Then-National Security Communications Adviser John Kirby mentioned that the U.S. had informed Ukraine about the situation.
