South Korea fired warning shots at a patrol unit from North Korea Monday morning for getting dangerously close to the dividing line in the second border incident between the countries in two months, according to CNN.
Soldiers from South Korea open fired on ten soldiers from the North as they approached the Military Demarcation Line situated northwest of Seoul, an unidentified South Korean Defense Ministry official told the station.
"After a warning broadcast, the South Korean side fired about 20 rounds of warning shots," the official said.
The North Korean soldiers did not respond with shots of their own but lingered around the line dividing the two nations for about three more hours before leaving, the official told CNN.
Exchange of warning shots between the two countries occur every now and then, including one incident in October when the South's military fired at North Korean soldiers for approaching the border, South Korea's Defense Ministry said.
In March, hundreds of shells were exchanged between both sides across their western sea border, CNN reported. A deadly incident occurred in November 2010 when four people were killed after North Korea open fired on the South's Yeonpyeong Island. North Korea claimed it as responding to a military drill on the island.
Tensions between the two nations stem from a war in the early '50s, which involved the U.S. and technically never ended. A ceasefire was agreed to in 1953, but an official peace treaty was never signed. The United States is also technically still at war with the North.
