Four North Korean soldiers fired 40 rounds at a comrade fleeing into South Korea and hit him five times in the first shooting at the jointly controlled area of the heavily fortified border since 1984, the South's military said on Tuesday.
South Korean soldiers did not fire their weapons, but Monday's incident occurred at a time of high animosity over North Korea's nuclear program, and Pyongyang has expressed intense anger over past high-profile defections.
The soldier is being treated at a South Korean hospital after a five-hour operation for the gunshot wounds he suffered during his escape across the Joint Security Area.
His personal details and motive for defection are unknown and his exact medical condition is unclear.
South Korea's military said he suffered injuries in his internal organs, but wasn't in a life-threatening condition. But the Ajou University Medical Center near Seoul said the soldier was relying on a breathing machine after the surgery removed the bullets. Lee Guk-jong, a doctor who leads Ajou's medical team for the soldier, described his patient's condition as "very dangerous", and said the next 10 days might determine whether he recovers.
On Monday, he first drove a military jeep before he left the vehicle after one of its wheels fell into a ditch. He then fled across the Joint Security Area (JSA), with fellow soldiers chasing and firing at him, South Korea's military said, citing unspecified surveillance systems installed in the area.
Suh Wook, chief director of operations for the South's Joint Chiefs of Staff, told lawmakers that North Korean soldiers fired a total of 40 rounds in a shooting that his office said was believed to have started while the soldier was in the jeep.
The soldier was found beneath a pile of leaves on the southern side of the JSA and South Korean troops crawled there to recover him.
The North's official media hasn't reported about the case, but it previously accused Seoul of kidnapping or enticing its citizens to defect.
About 30,000 North Koreans have fled to South Korea since the end of the 1950-53 Korean War, most travel via China.
JSA and The History of Defections
About 30,000 North Koreans have fled to South Korea since the end of the 1950-53 Korean War, most travel via China.
The JSA is jointly overseen by the American-led UN Command and by North Korea, with South Korean and North Korean border guards facing each other only metres apart. There is a cluster of blue huts straddling blocks of concrete that forms the border line and other buildings in the area.
It's located inside the four-kilometre-wide (two-and-a-half-mile wide) mine-strewn Demilitarised Zone, whose northern and southern boundaries are guarded by barbed wire fences and combat troops. It's created as a buffer zone when the three-year Korean War ended with an armistice in 1953.
Monday’s shooting was the first at the Joint Security Area since North Korean and UN Command soldiers traded gunfire when a Soviet citizen defected by sprinting to the South Korean sector of the JSA in 1984.
A North Korean soldier defected there in 1998 and another in 2007, but neither of those events involved gunfire between the rivals, according to South Korea's military.
The 1984 exchange of gunfire happened after North Korean soldiers crossed the border and fired, according to the UN Command. In Monday's incident, it wasn't known if the North continued firing even after the defector was officially in the southern part of the Joint Security Area. The UN Command said on Tuesday that an investigation into the incident was underway.
The Joint Security Area was the site of some bloodshed during the Cold War, but there hasn't been major violence there in recent years.
In 1976, when North Korean soldiers axed two American army officers to death and the United States responded by flying nuclear-capable B-52 bombers toward the DMZ in an attempt to intimidate the North.
