Iran Covers More Tunnel Entrances at Isfahan Nuclear Site

Iran has covered additional tunnel entrances at its nuclear site in Isfahan. Images analyzed by the Institute for Science and International Security (ISIS) in January revealed the covering of two more tunnel entrances with soil.

This activity occurs amidst ongoing discussions between US and Iranian officials, set against a backdrop of heightened tensions between the two nations.

Strategic Implications of Backfilling

ISIS states that backfilling tunnel entrances could mitigate the impact of potential airstrikes. It could also complicate ground access for special forces aiming to seize or destroy highly enriched uranium that might be stored inside the tunnels.

Precedent for Such Preparations

Previous similar preparations were observed at Iran's nuclear facilities in Isfahan, Fordo, and Natanz before US strikes occurred in June of the previous year.
