South Korea fires warning shots at North Korean troops crossing border

South Korea has fired warning shots at North Korean troops who crossed the border between the two countries. This incident occurred as the South Korean President is set to visit the United States and Japan. According to the report, North Korea's state media has described the South Korean action as a "deliberate provocation." The details of the incident, including the exact location and the number of North Korean troops involved, have not been provided. The border between South and North Korea remains one of the most heavily militarized in the world, and such incidents are not uncommon. However, they have the potential to escalate tensions between the two nations, which have been divided since the end of the Korean War in 1953. The South Korean leader's visit to the US and Japan is expected to focus on regional security and economic cooperation, and this latest border incident is likely to be a topic of discussion during the diplomatic meetings.
