class="story-body__introduction">A North Korean who defected at the heavily guarded Demilitarised Zone was shot at least five times and is in a critical condition, South Korea says, according to BBC.The soldier crossed to the South Korean side of the Joint Security Area (JSA) in the village of Panmunjom on Monday. He had driven near the JSA, but had to finish his journey by foot when a wheel came loose, the South said. North Korean troops shot at him 40 times - but he made it across and was found under a pile of leaves, it added. About 1,000 people from the North flee to the South each year - but very few defect via the Demilitarised Zone (DMZ), which is one of the world's most heavily guarded strips of land. It is even more unusual for North Koreans to cross at the JSA, which is a tourist attraction, and the only portion of the DMZ where both forces stand face-to-face. North and South Korea are technically still at war, since the conflict between them ended in 1953 with a truce and not a formal peace treaty. Five bullets extracted South Korea's military gave more details of the soldier's condition on Tuesday. "Until this morning, we heard he had no consciousness and was unable to breathe on his own - but his life can be saved," military official Suh Uk told lawmakers. Doctors had extracted five bullets from his body, but suspected there were two more inside, he added. The soldier had been spotted driving towards the JSA on Monday afternoon - but a wheel came off, South Korea's Joint Chiefs of Staff said. "He then exited the vehicle and continued fleeing south across the line as he was fired upon by other soldiers from North Korea," the US-led United Nations Command said. The defector took cover behind a building on the South Korea side - troops later found him collapsed under a pile of leaves, and crawled to the spot to recover him, the military added. South Korea's defence minister Song Young-moo told lawmakers that it was the first time North Korean soldiers had shot into the South's side of the JSA. Some MPs questioned whether this meant North Korea had violated the terms of the armistice agreement between the two sides, Yonhap news agency reported.
