Seoul warns of N. Korea border escalation as Pyongyang raises threats

South Korea's defense ministry voiced 'grave concern' over North Korea's heightened border tensions, which include threats and increased military activity along the DMZ. The statement follows a pattern of recent provocations, but the specific trigger for this escalation remains unclear. This matters as it signals potential for miscalculation on the Korean Peninsula, with implications for regional stability and US-ROK alliance posture.
