Iran buries nuclear site entrances amid rising tensions with the U.S.

Satellite images reveal that Iran has buried all three tunnel entrances at its Isfahan nuclear complex. Analysts say the move mirrors defensive preparations taken before U.S. airstrikes devastated the facility last year, with no vehicle or personnel activity visible around the entrances.

The burial appears aimed at limiting damage from potential airstrikes and complicating any ground raid targeting enriched uranium stored in the underground facility. Experts suggest equipment or materials may have been moved into the tunnels for protection, though this remains unconfirmed.

The fortification comes amid ongoing U.S.-Iran tensions. President Trump has demanded Iran curb its nuclear program, warning of military action, while Tehran insists halting uranium enrichment is unacceptable. Recent indirect talks in Oman showed little progress toward a new deal.
