Israel National News reports: “High-resolution satellite imagery of Iran’s Isfahan nuclear complex, taken on Sunday and published on Monday by the Institute for Science and International Security, reveals significant changes around the site’s tunnel entrances.

The images show that the middle and southern entrances have been completely covered with soil, making them unrecognizable. The northernmost entrance, which features additional passive defense measures, has also been backfilled with soil.

The Institute for Science and International Security said that the alterations suggest Iran is taking steps to protect the facility from potential US or Israeli aerial strikes or ground raids. It noted that backfilling the tunnels would dampen the effects of airstrikes and complicate special forces operations intended to seize or destroy sensitive materials, such as highly enriched uranium, that may be stored in the tunnels. While it cannot be confirmed, it is possible that Iran has moved equipment or materials into these tunnels for protection, said the organization.

It also noted that similar preparations were observed just before Operation Midnight Hammer this past June, in which the US joined Israel and struck the nuclear facilities at Fordow, Natanz, and Isfahan…”
