North and South Korean soldiers enter each other's territory
North invades the South
The North invaded the South in 1950, triggering the Korean War, and Seoul went on to change hands four times as Pyongyang's Chinese-backed forces and the US-led UN troops supporting the South fought their way up and down the peninsula and back again.

The fight
South Korean inspectors visited each of the guard posts on the North's side to make sure they had been dismantled and all firearms and troops removed.
North Korean inspectors carried out the same process at the South's bunkers in the afternoon.

Military demarcation line
Led by the North Koreans, the Southerners walked along a path where the North's guard posts had once stood, soldiers from both sides taking photos and filming the process as they chatted.
"This marks the first time since the division that the soldiers of the North and South... are peacefully crossing the military demarcation line," the ministry said.

North vs South
Despite its name, the area around the DMZ is one of the most fortified places on earth, replete with minefields and barbed-wire fences.
But under the plans to ease tensions agreed in Pyongyang, the two Koreas have demilitarised the border truce village of Panmunjom, leaving it manned by 35 unarmed personnel from each side.
