The senior Israeli source said intelligence indicated that the enriched uranium had not been moved from the Fordo, Natanz, and Isfahan facilities prior to the strikes — and hasn't been relocated since.

Israel believes that Iran could potentially retrieve enriched uranium buried beneath one of the three facilities struck by US forces last month, according to a senior Israeli official.

The United States decisively entered into conflict with Iran on Saturday after President Donald Trump ordered US warplanes to drop massive bombs on three nuclear sites inside the country, thrusting him squarely into an escalating Middle East conflict even as he holds out hope the matter can be resolved diplomatically.
