The escalating situation between North and South Korea dates back to the Korean War, which ended in 1953 without a formal peace treaty, resulting in ongoing tensions. South Korea's Joint Chiefs of Staff reported that North Korean troops crossed the military demarcation line around 15:00 local time on Tuesday but retreated shortly after, prompting the warning shots. North Korean Army Lt Gen Ko Jong Chol described the actions by Seoul’s military as a serious provocation that could drive the situation towards uncontrollable levels. In June, President Lee campaigned for improved inter-Korean relations and even suspended propaganda broadcasts directed at the North, which Pyongyang views as acts of war. The international community is closely monitoring the developments as diplomatic efforts remain fraught with challenges.
