North Korean leader Kim Jong Un has inspected a facility that produces nuclear material and called for bolstering the country’s nuclear capability, state media reports.

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.
