North Korea is boosting nuclear weapons capacity: IAEA chief

North Korea has made “very serious” advances ‌in its abilities to turn out nuclear weapons, with the probable addition ​of a new uranium enrichment facility, as it stepped up activity at ⁠a key complex, IAEA chief Rafael Grossi said on Wednesday (April 15, 2026).

Enriching uranium can provide an alternative, and experts say, a more effective, path to acquiring weapons-grade material in addition to reprocessing spent plutonium extracted from ‌a nuclear reactor.
