In brief
Inside the tightly guarded Yongbyon complex, satellite imagery has unveiled a covert two-storey building capable of housing 28 centrifuge cascades, marking North Korea’s latest expansion of its uranium enrichment capability. The International Atomic Energy Agency (IAEA) warns that the new facility profoundly violates UN Security Council resolutions and signals a deepening nuclear‑weapons programme. Kim Jong Un’s recent appearance at a “newly inaugurated” enrichment site further underscores the regime’s commitment to advancing its arsenal. Experts point to other hidden sites such as Kangson, suggesting a broader network of clandestine production. The revelation comes as South Korea pushes for war‑end talks and international arms‑control measures.
Satellite reconnaissance released by the International Atomic Energy Agency (IAEA) shows a newly constructed two-storey building within the Yongbyon nuclear complex. The facility is engineered to house up to 28 centrifuge cascades, a significant expansion of North Korea’s uranium enrichment capacity.
IAEA Director Rafael Grossi described the development as a “clear violation of relevant UN Security Council resolutions” and a “deeply regrettable” escalation of the DPRK’s nuclear programme.
Earlier this year, Kim Jong Un visited a “newly inaugurated nuclear materials production factory” at Yongbyon, praising the country’s “greatly expanded production capacity” and signalling readiness for larger strategic plans.
Analysts note that the North’s nuclear infrastructure is not limited to Yongbyon. In January, the agency spotted operational activity at an annex in Kangson, near Pyongyang, where construction began in 2024.
Despite North Korea’s economic hardships, estimates from a 2022 think‑tank suggest the regime invested roughly USD 640 million annually into its secretive weapons programme.
Regional implications: South Korea’s President Lee Jae Myung recently urged talks on ending the Korean war and halting North Korea’s nuclear escalation. The regime has yet to respond to these overtures.
With a record of missile tests and six nuclear weapons tests completed by September 2017, the expanded enrichment capability threatens a rapid leap toward new weapons.
