http://www.bbc.com/news/world-asia-42076543 A pursuing North Korean soldier violated the 1953 Armistice by crossing into South Korea before realizing what he'd done and turning around. These pursuing North Korean soldiers initiated hostile military action within the village, another breech of the Armistice. Several of the rounds fired crossed the DMZ into the South Korean zone, again, a breech of the Armistice. I suspect the UN Command is putting this out to forestall any attempt by the North to demand the return or claims that the defector was kidnapped. But, still, the last major incident in the area was 40 years ago.
