"This is a violation of the armistice agreement", a South Korean military official said in the Korea JoonAng Daily. "It's also tough for South Korea to pursue contact with North Korea single-handedly".
The soldiers fired their weapons and crossed the border in their attempts to catch the defector.
Right at the line that divides North from South, the defector crashes the jeep into a ditch.
Americans have been occasionally arrested after entering North Korea illegally from China but a US citizen trying to get in from South Korea is unusual. In the gunfire during his escape, he was shot five times.
During the incident, one North Korean soldier appeared to cross the MDL for a few seconds, and then run back towards the northern side of the line. The defector falls stretched out and unmoving in a pile of leaves against a small wall on the South Korean side.
The entire sequence, from the first appearance of the jeep to the soldier's frenzied crossing, lasts four minutes. Not far away, heavily armed North Korean troops begin to gather near the Kim Il Sung monument.
The video shifts again. Then three South Korean soldiers crawled out and dragged him to safety. The bullets went in only one direction.

The Korean Central News Agency reported that North Korean leader Kim Jong-un conducted on-the-spot-guidance at the Sungri Motor Plant in Tokchon, South Pyongan Province on Nov. 21.
Although the defector's name and rank have not been disclosed, he is believed to be in his mid-20s and a staff sergeant in the KPA.
Lee told a news conference on Wednesday that the man had regained consciousness and was now stable. His doctor said Wednesday he is enjoying watching American movies and shows such as "Transformers", "CSI", and "Bruce Almighty", and listening to South Korean pop songs such as "Gee" by popular female band "Girls' Generation".
"His condition has become much better since yesterday".
China's foreign ministry said it has no issues with implementing international sanctions, and that the sanctions are being actively enforced. South Korean officials said he told them he wanted to help resolve the dispute.
While treating the wounds, surgeons earlier removed dozens of parasites from the soldier's ruptured small intestine, including presumed roundworms that were as long as 27 centimeters (10.6 inches), which may reflect poor nutrition and health in North Korea's military.
Changing attitudes, increased public scrutiny and fears of facing lawsuits also have caused schools to take action, anti-hazing advocates say. "As interaction resumes after the break, we can expect to see more examples [of these meetings] in the future", Yang predicted.
