Iran fortifies Isfahan nuclear site as 400 kilos of enriched uranium go missing

Iran’s Isfahan nuclear complex has suddenly gone quiet just as war fears climbed, with new satellite images showing tunnel entrances buried, defenses reinforced and vehicle activity gone. Analysts warned the fortifications looked like preparation for fresh U.S. or Israeli strikes—especially after Tehran claimed unexploded American bunker‑busters still sat inside its nuclear sites. At the same time, 400 kilos of highly enriched uranium had remained unaccounted for, even as Iran had offered to dilute 60% stock in return for full sanctions relief. With jets moving and talks in Oman, the next move had stayed unclear.
