North Korean leader Kim Jong Un described South Korea as foreign and hostile nation, state media KCNA reported on Friday, with photos showing Kim and high-ranking military officials at a command post looking at a map labeled "Seoul," Reuters reported, citing News.bg.
The report comes a day after KCNA reported that North Korea had changed its constitution to designate South Korea as a "enemy state" and has rejected the unification of the two countries as a goal.
Kim has increasingly attacked South Korea this year, accusing Seoul of conspiring with Washington to topple his regime.
Pyongyang blew up road and rail links with South Korea this week. These actions highlighted "not just physical closure" on the border "but also the end of bad relations with Seoul", KCNA quoted Kim as saying.
Seoul has said that if North Korea harms the safety of its people, "that day will be the end of the North Korean regime.
Kim made the remarks while inspecting the headquarters of the North Korean army's 2nd Corps on Thursday, KCNA said. During the visit, he also pointed out that the changed nature of the South Korea-US alliance and their different, more advanced military maneuvers underscore the importance of a stronger North Korean nuclear deterrent.
South Korea has said its policy is to continue to pursue national unification, but to respond with force if North Korea undertakes any aggression.
