North Korean leader Kim Jong Un toured a uranium enrichment facility to inspect nuclear weapon production plans, according to state media on Friday. He also oversaw military special forces exercises and a tactical nuclear rocket test using a new launch vehicle.

The Rodong Sinmun reported that Kim visited the Nuclear Weapons Institute and a “weapons-grade nuclear materials production base,” where he “presented important tasks for the long-term plan to increase the production” of nuclear weapons.

Photos showed Kim walking past rows of centrifuges at the unnamed enrichment facility, the first time state media has shown Kim at such a site.
