The North Korean People's Army has threatened to attack lighting equipment used by South Korean and American troops in the Demilitarized Zone dividing the two Koreas. North Korean authorities claim U.S. and South Korean troops have been carrying out "deliberate provocations" by aiming their lights at North Korean guard posts in the area. "Floodlight directed at the KPA side at random is taken as an intolerable means of provocation and it will be the target of merciless pinpoint shots," the NPA said in a statement released Saturday. "The true aim sought by the provocateurs through their recent act is to seriously get on the nerves of the KPA soldiers, lead them to take due countermeasures and label them as provocation," it said, warning that the "provocations" come as Korea is at the "brink of war" over U.S. and South Korean military drills. North Korea insists that the annual drills are actually preparations for an impending invasion. The NPA's statement came after the United Nations Security Council earlier this week condemned four North Korean missile launches carried out in the past two months.
