New satellite imagery indicates that Iran has buried all tunnel entrances to its Isfahan nuclear site, raising concerns that Tehran is preparing for potential military strikes or covert raids.

According to the Washington-based Institute for Science and International Security, recent images show that two tunnel entrances are completely covered with soil, while a third has additional protective measures. The group also reports no visible vehicle activity near the entrances.

Analysts believe the move is intended to shield sensitive materials from airstrikes or special forces operations by the United States or Israel. Backfilling the tunnels would make it more difficult to access or destroy any highly enriched uranium that may be stored underground.

The institute noted that similar preparations were observed shortly before past military operations targeting Iranian nuclear facilities, including sites at Fordow and Natanz.

Prior to Israel’s 12-day war with Iran in June, the Islamic Republic operated three major nuclear facilities tied to its enrichment program. The Isfahan site has been primarily used to produce uranium gas, a key component in nuclear fuel production.

Earlier satellite images showed new roofs being built at the site, which analysts believe may have been part of an effort to recover materials or conceal activity without revealing what was removed.

U.S. President Donald Trump has repeatedly demanded Iran negotiate limits on its nuclear program, warning that continued defiance could trigger American military action.

The new imagery adds to growing international concern over Iran’s intentions and the future of diplomatic efforts to curb its nuclear ambitions.
