North Korea has made a “very serious” advance in its ability to produce nuclear weapons, according to IAEA chief Rafael Grossi. He reported significant increases in activity at key facilities, particularly the Yongbyon nuclear complex, which includes a five-megawatt reactor and a uranium reprocessing unit. During his visit to Seoul, Grossi noted that these developments "point to a very serious increase in the capabilities of (the) DPRK" in the area of nuclear weapons production, estimating that North Korea's arsenal consists of a few dozen warheads, according to Reuters, Channel News Asia, Al Jazeera, India Times, and South China Morning Post.

The IAEA has observed increased operations at the Yongbyon reactor, light-water reactor, and a new uranium enrichment facility, which experts argue signifies a more effective means of acquiring weapons-grade material compared to traditional plutonium reprocessing. "In our periodic assessments, we have been able to confirm that there's a rapid increase in the operations," Grossi said, emphasizing that the construction indicates a strategic expansion of North Korea's weapons production capabilities, according to Reuters, Channel News Asia, Al Jazeera, India Times, and South China Morning Post.

Despite concerns about potential support from Russia, Grossi stated that, based on the IAEA's observations, there is no evidence of direct technological assistance from Russia towards North Korea's nuclear ambitions. He added that North Korea's decision to expel IAEA inspectors in 2009 complicates the agency's ability to directly monitor developments in the country. This environment of secrecy surrounding nuclear capabilities raises ongoing concerns about regional security and global nuclear proliferation, according to Reuters, Channel News Asia, Al Jazeera, India Times, and South China Morning Post.
