Peninsula divided – As part of the terms of the armistice that ended the Korean War in 1953, the opposing armies pulled back their frontline positions to create a 4-km-wide demilitarized zone. CNN cameraman Brad Olson shares his images of the DMZ.
Neutral venue – When the two Koreas meet for talks, they do so in the Joint Security Area (JSA) in Panmunjun, an abandoned village that straddles the DMZ.
On edge – Our guide stressed to us that we were in an active war zone and should not surprise the other side with "sudden actions" such as shouting and gesturing. We were also made to stay within a very limited area.
On guard – One North Korean soldier observes us closely with his binoculars through the icicles.
Inside the North – We visited a high point overlooking Kijongdong village, which is located about 2 km away on the North Korean side within the DMZ.
Just for show – The village of Kijongdong is located on the North's side of the DMZ. South Korean troops refer to it as a "Propaganda Village," as they believe it is largely uninhabited and just for show.
Full mast – A North Korean flag flies over the village of Kijongdong. It must be one of the tallest flagpoles in the world.
Bridging the divide – The Bridge of No Return is where prisoner exchanges were held at the end of the Korean War. We were warned again not to stray into restricted areas or make any sudden gestures. Pointing is considered a hostile act here.
Just watching – On the other side of the bridge, we spotted some North Korean soldiers looking back from behind the barbed wire, as well as a farmer herding goats in the field.
