North Korean leader Kim Jong-un has visited a newly operational nuclear material production facility and called for an "exponential" expansion of the country's atomic arsenal, state media reports.
Kim said production capacity for weapons-grade nuclear material had reached more than double its previous level over the past five years and instructed officials to further increase output to meet long-term strategic goals.
During the visit, Kim was briefed on new production processes incorporating more advanced technology and reviewed current output targets and future plans, KCNA said on Thursday.
