Recently, the grass and trees near the Military Demarcation Line have completely... vanished?!

This is because North Korean troops have cleared the entire area.
In their place, a new road stretching alongside the frontline has appeared.

Suspicious movements by North Korean troops taking place within the Demilitarized Zone
are even being called a serious security crisis...

The Military Demarcation Line (MDL) may soon transform
from a truce line into a national border.

SBS News analyzed North Korea's border-building operations
