Decades after war, North Korea still builds borders, draws warning shots

SEOUL — Seventy four years after the Korean War began, North Korean troops are building new fortifications, occasionally inviting warning shots from South Korean counterparts across a border that has been frozen in a state of war.

In recent weeks, North Korea has deployed a large squad of soldiers to build what appeared to be anti-tank barriers, plant land mines and reinforce tactical roads within the heavily armed Demilitarised Zone (DMZ), according to the South's military.
