Israel believes at least some of Iran’s highly enriched uranium was buried by U.S. strikes and not destroyed or moved beforehand.

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.

Some of Iran’s underground stockpile of near-bomb-grade enriched uranium survived U.S. and Israeli attacks last month and may be accessible to Iran’s nuclear engineers, according to a senior Israeli official.
