In a significant escalation of tensions on the Korean Peninsula, North Korea has announced its decision to completely cut off all road and rail links to South Korea. This move comes amid heightened military activity and a key parliamentary meeting, where North Korea's leadership discussed constitutional changes aimed at solidifying its defensive posture. The North has vowed to permanently block the border with the South and invest in front-line defense structures. This announcement follows a series of declarations by North Korean officials, asserting the establishment of a 'two state system' and indicating plans to fortify their border. The situation reflects a sharp deterioration in inter-Korean relations, underscoring the ongoing confrontation between the two nations.
