North Korea has offered a rare glimpse into a secretive facility to produce weapons-grade uranium as it says leader Kim Jong Un visited the area and called for stronger efforts to increase the number of the country's nuclear weapons. It’s unclear if the site is at the North’s main Yongbyon nuclear complex, but it’s the first disclosure of a uranium-enrichment facility since North Korea showed one at Yongbyon to visiting American scholars in 2010. The latest unveiling is likely an attempt to apply more pressure on the U.S. and its allies. However, the images North Korea’s media released of the area could help outside experts improve their estimates of North Korea's nuclear production.
