Overview
- High‑resolution imagery published this week shows the Isfahan complex’s middle and southern tunnel entrances fully buried and the northern entrance backfilled, with no vehicle activity indicating the work appears complete.
- The Institute for Science and International Security assesses the steps as defensive measures intended to dampen airstrikes and complicate special‑forces raids on sensitive materials.
- Planet Labs images reported by the Associated Press show new roofs over damaged buildings at Isfahan and Natanz that block overhead views while Iran continues to bar IAEA inspectors.
- The watchdog notes similar tunnel‑sealing activity was seen before June’s Operation Midnight Hammer strikes on Fordow, Natanz, and Isfahan, suggesting a recurring hardening pattern.
- The U.S. Maritime Administration advised U.S.‑flagged ships transiting the Strait of Hormuz to stay as far as possible from Iranian waters and decline boarding attempts, reflecting elevated regional tensions alongside renewed indirect U.S.–Iran talks in Oman.
