South Korea Fires Warning Shots After Third Border Breach by North's Troops.

South Korean soldiers fired warning shots after North Korean troops crossed the border and then retreated, marking the third such incident this month. The incident occurred shortly after Russian President Vladimir Putin's visit to North Korea, during which a major deal was reached between the two countries. Tensions along the border have been rising, with North Korea increasing its military presence in the buffer zone. The recent exchange of actions between the two Koreas raises concerns about the potential escalation of a small incident and the involvement of US military personnel stationed in South Korea.
