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.

An Israeli military official said on Tuesday that Iranian air strikes last month had hit some Israeli military sites, the first such apparent public acknowledgement that such locations had been struck.

For the first time, an Israeli military official has acknowledged that “very few” of their military sites were hit by Iranian missiles during the recent 12-day war, though the damage was minimal and the bases remained functional.
