The demilitarized zone (DMZ) between North Korea and South Korea extends for approximately 150 miles (240 km) across the Korean Peninsula.1

This buffer zone was established following the Korean War by requiring forces to withdraw 1.2 miles (2 km) from each side of the military demarcation line. It stretches from the mouth of the Han River on the west coast to the vicinity of the North Korean town of Kosŏng on the east coast.1
