SEOUL, South Korea (AP) — The influential sister of North Korean leader Kim Jong Un has warned the United States that it would face “a more fatal security crisis” as Washington pushes for U.N. condemnation of the North’s recent intercontinental ballistic missile test. Kim Yo Jong’s warning Tuesday came hours after the U.S. ambassador to the United Nations read a statement by 14 countries which supported action to limit North Korea’s advancement of its weapons programs. Kim called that statement “disgusting” and “a wanton violation of our sovereignty.” North Korea on Friday tested it most powerful Hwasong-17 missile, which some experts say could potentially strike anywhere in the U.S. mainland.
