North Korea shows off a new facility for processing uranium as it plans to grow its nuclear program.

North Korea has shown a secretive uranium-enrichment facility during a visit by leader Kim Jong Un, where he urged the production of nuclear weapons to be increased. This facility may be located at the Yongbyon nuclear complex, a site shown to U.S. scholars back in 2010. The photos released by North Korean media may provide important clues about the country's nuclear capabilities and production levels of nuclear materials.

Kim Jong Un expressed satisfaction with North Korea's nuclear technology during his visit to the Nuclear Weapons Institute. Photos depict him inspecting lines of centrifuges and discussing with scientists, though the exact location and timing of his visit are not disclosed.

Kim emphasized the urgent need to grow the numbers of centrifuges to rapidly increase nuclear weaponry for defense. He has commanded acceleration in adopting advanced centrifuge technology, reaffirming his commitment to enhancing preemptive attack capabilities against threats from the U.S.

South Korea has condemned North Korea's ongoing efforts to expand its nuclear arsenal, stating it is a grave threat to global peace and in direct violation of U.N. sanctions. North Korea has had encounters with international experts in the past, disclosing operations of thousands of centrifuges at Yongbyon.

Experts believe that the publicly released images of the North Korean facility will help them better estimate the quantity of bomb-making material North Korea has accumulated. Furthermore, North Korea's recent actions suggest a growing boldness in their nuclear ambitions, prompting concerns over their increasing capability to produce highly enriched uranium.
