North Korea unveiled new, smaller nuclear warheads and vowed to produce more weapons-grade nuclear material to expand its arsenal, state media said on Tuesday, as a U.S. aircraft carrier arrived in South Korea for military drills.
North Korea's Korean Central News Agency (KCNA) released photos of the warheads, dubbed Hwasan-31s. Leader Kim Jong Un visited the Nuclear Weapons Institute and inspected new tactical nuclear weapons and technology for mounting warheads on ballistic missiles, as well as nuclear counterattack operation plans, KCNA said.
