North Korea has built a new two-storey uranium enrichment facility, the head of the world's nuclear watchdog said this week, calling it a cause for "serious concern".

The new building is part of the main Yongbyon nuclear complex, and reportedly capable of housing up to 28 centrifuge cascades used to enrich uranium.

In a report published late last month, the International Atomic Energy Agency said Pyongyang has also begun operating an expanded annex at another enrichment site.

These findings point to a steady expansion of the North's sancitoned nuclear infrastructure. The agency, which has no inspectors in North Korea since it was expelled in 2009, relies on satellite imagery for assessments.
