North Korean leader Kim Jong Un has accused the United States of ramping up tension and provocations, saying the Korean peninsula has never faced a greater risk of nuclear war, state media KCNA said on Friday.

Kim Jong Un warned U.S. that increasing tensions between the countries could lead to thermonuclear war sooner rather than later.

Kim claimed the U.S. had engaged in a “hostile and aggressive” policy with his country and that, as a result, the two countries had never been closer to nuclear war than now, according to reports from KCNA,
