North Korea's National Peace Committee said the regime would target South Korea's presidential office of Cheong Wa Dae, the White House, and the Pentagon, with their most advanced rockets and missiles, if South Korea and the U.S. go ahead with two weeks of joint military exercises in mid-August.
The Ulchi-Freedom Guardian drills are held every year and are designed to improve joint defenses against North Korea.
But this year's is different in that it focuses more on a deterrence strategy aimed at North Korea's nuclear threats.
North Korea said testing the deterrence strategy plan is just like a declaration of war against Pyongyang.
The committee said inter-Korean relations were at risk of collapsing completely, and that the Korean peninsula is in a volatile situation.
South Korea's defense ministry shrugged off the North's threat on Friday and said the exercise would go on as planned, reiterating that they are completely defensive in nature.
The ministry also called out North Korea for its recent series of missile launches and increasingly hostile rhetoric, saying they've gone too far.
