North Korea is clearing vegetation at six different areas across the peninsula’s demilitarized zone (DMZ) in apparent efforts to bolster border defenses on South Korea’s doorstep, analysis of satellite imagery by NK News reveals.

NK News reported earlier this week on a section of borderland cleared by North Korea on the east coast of the peninsula, but further analysis revealed DPRK soldiers are clearing sections all along the inter-Korean border, spanning from east to west on the Korean Peninsula.
