S enior Israeli officials are acknowledging that some enriched uranium may have survived the powerful U.S. strikes on Iran's key nuclear sites last month.

A senior Israeli official says Israel believes deeply buried stocks of enriched uranium at one Iranian nuclear facility hit by the U.S. military are potentially retrievable.

Hammer involved a coordinated strike using GBU-57 bunker-buster bombs delivered by B‑2 bombers and submarine-launched Tomahawks, targeting the Isfahan, Natanz, and Fordow nuclear sites.
