Several American media outlets referred to sources with insight into the intelligence report late on Tuesday. The first analyses show that the entrances to the Iranian nuclear facilities were destroyed in the American bombing raids.
However, the damage to the facilities themselves is not as extensive as previously stated.
President Donald Trump has gone so far as to say that the facilities have been "completely and totally destroyed".
First evaluation
Both CNN and The New York Times claim to have received a report on the first evaluation, made by the Defense Intelligence Agency (DIA), which is the Pentagon's intelligence service.
The results of the evaluation are based on information from the US regional military headquarters US Central Command, according to sources that the two media organizations have spoken to separately.
Two of the sources say that Iran's stockpile of enriched uranium was not destroyed. One source claims that the centrifuges used to enrich uranium are "intact".
The conclusion from the DIA is that the US has managed to set back (Iran's nuclear energy program) a few months, says a source to CNN who was the first to refer to the report.
On Tuesday, the Trump administration announced that a briefing on the attacks on Iran, which was to be held for selected members of the US Congress on Tuesday, has been postponed until Thursday. The reason given was that Defense Secretary Pete Hegseth and Foreign Minister Marco Rubio would be able to participate, according to sources who spoke to the news agency AP.
"Slandering Trump"
The White House and the Pentagon were quick to question the reporting on the first, preliminary evaluation of the bombing in Iran.
The Pentagon releases a statement from Defense Secretary Hegseth in which he says that "based on everything we've seen - and I've seen everything - our bombing operation destroyed Iran's ability to construct a nuclear weapon", writes BBC.
The White House denies the allegations entirely. Spokesperson Karoline Leavitt called them "completely incorrect".
"Everyone knows what happens when you drop (these specific) bombs perfectly on target: total destruction", she wrote in a statement on Tuesday evening and claimed that the allegations were an attempt to slander Trump.
The spokesperson for the US State Department, Bruce Tammy, was somewhat more cautious in her statement at the evening's press conference, she was content to say that Iran "will not have a nuclear weapon".
