Experts say ‘deeply’ concerned over Iran’s work at underground nuclear site

Experts warn that Iran's continued construction at the IAEA-uninspected Pickaxe Mountain facility in the Zagros Mountains raises concerns about compliance with the Trump-era MOU. Satellite imagery from June 2026 shows ongoing activity at the site, which analysts suggest could become a nuclear enrichment plant if negotiations fail. The IAEA has not responded to queries about seeking access to the facility.
