The IAEA said it has observed construction activity at Pikeh Zoushan, a heavily
fortified site south of Tehran's main uranium-enrichment plant suspected of
nuclear-related activity. Director General GROSSI said the agency has not
inspected the tunnel complex; remote-sensing imagery shows new movement and
signs of activity around the construction site, but there is no specific
information on what is occurring inside. His comments followed the IAEA's
referral of Iran's nuclear file to the UN Security Council for non-compliance
with nuclear-related obligations. Since June 2025, after Israeli and US strikes
on Iran's large nuclear facilities, IAEA inspectors have been unable to verify
the status or location of Iran's near‑weapons‑grade uranium stocks. Former US
president Trump referenced the site publicly at least twice in the past week.
