North Korea building border ‘wall’, satellite images reveal

North Korea is building sections of what appears to be a wall in several places near its border with South Korea, new satellite images reveal.

The DMZ is a 4km (2.5 miles) wide buffer zone between North and South Korea, who are still technically at war having never signed a peace treaty. The DMZ is split in two, with each side controlled by the respective nations.

This recent activity is “unusual”, according to experts, and comes at a time of rising tensions between the two countries.
