Kim Jong Un has inspected a facility that produces nuclear material and called for bolstering the country’s nuclear capability.

U.S. President Donald Trump said in an interview broadcast on Thursday that he plans to seek to engage North Korean leader Kim Jong Un anew after the two men developed a working relationship in Trump's first term.

North Korea has test-fired sea-to-surface strategic cruise guided missiles, the North's state media reported Sunday, quoting Kim as saying that Pyongyang's deterrence means are being perfected.

North Korea's foreign ministry vowed the "toughest counteraction" against the United States as long as Washington "refuses" the country's sovereignty.

North Korea announced it had performed a test of its cruise missile system on Saturday. It was the communist country’s fourth known missile launch since November and the second in less than a week since President Donald Trump’s inauguration.
