Israel believes deeply buried stocks of enriched uranium at one Iranian nuclear facility hit by the U.S. military are potentially retrievable, a senior Israeli official said, Associated Press reported.

And the agency that built the U.S. “bunker buster” bombs dropped on two other nuclear sites said Thursday that it is still waiting for data to be able to determine if those munitions reached their targets.

Both developments widen the views on the damage from last month’s strikes, when the United States inserted itself in Israel’s war in a bid to eliminate the threat of Iran developing a nuclear weapon. Iran says its program is peaceful. 

President Donald Trump is adamant that the U.S. strikes “obliterated” the three Iranian nuclear facilities it targeted. International assessments and an initial U.S. intelligence assessment have been more measured, with the U.S. Defense Intelligence Agency saying in a preliminary report that the strikes did significant damage to the Fordo, Natanz and Isfahan sites, but did not destroy them, according to Associated Press.
