Two days after the US had conducted strikes on three nuclear facilities in Iran, a BBC News website live page that had opened on June 22nd was retitled “US strikes did not destroy Iran’s nuclear programme, intelligence report says” and presented with a summary that now includes the following:
“US strikes on Iran’s nuclear facilities did not destroy the Iranian nuclear programme and have probably only set it back by months, according to an intelligence evaluation
Details of the initial damage assessment from the Pentagon’s Defense Intelligence Agency were leaked to the BBC’s US partner CBS and other media”
Entries based on those reports in the US media include:
Another live page was opened early on June 25th.
Also on June 25th, the BBC News website published a flurry of reports amplifying that story: [emphasis added]
“US strikes did not destroy Iran nuclear programme, says intelligence assessment” Nadine Yousif, 25/6/25
“The US strikes on Iran’s nuclear facilities did not destroy the country’s nuclear programme and probably only set it back by months, according to an early Pentagon intelligence assessment of the attack.
The Islamic Republic’s stockpile of enriched uranium was not eliminated in Saturday’s bombings, sources familiar with the Defense Intelligence Agency evaluation told the BBC’s US partner CBS. […]
According to CBS, officials familiar with the report warned it was an early assessment that could change as more information becomes available about the sites. It is also not clear at what confidence level the findings included in the report were made.
The US struck three nuclear facilities in Iran – Fordo, Natanz and Isfahan – with “bunker buster” bombs capable of penetrating 18m (60ft) of concrete or 61m (200ft) of earth before exploding.
But sources familiar with the Pentagon’s intelligence assessment say Iran’s centrifuges are largely “intact” and the impact was limited to above-ground structures. […]
The anonymous sources told US media it is estimated that the attack only set Iran back “a few months, tops”, and that any resumption of its nuclear programme may be based on how long it takes the country to dig out and make repairs. […]
Tehran has always said its nuclear programme is for peaceful purposes.”
“Damaged or destroyed – how much does leaked US report on Iran’s nuclear sites tell us?” Gordon Corera, 25/6/25
“A leaked Defence Intelligence Agency (DIA) assessment has suggested the core components of Iran’s nuclear programme have not been destroyed and the strikes only set back Iran’s efforts by months rather than years.
But that is only an initial assessment and labelled as “low confidence” – the tag comes because it is early days in trying to understand what happened at a place that is deliberately hidden from prying eyes. […]
“Trump pushes back after leaked report suggests Iran strikes had limited impact” Rachel Hagan, 25/6/25
“On Tuesday, sources familiar with the initial report into Saturday’s bombings told the BBC’s US news partner CBS that Iran’s stockpile of enriched uranium had not been eliminated.
They added that the strikes had only set the country’s nuclear programme back by a few months – an assessment the White House swiftly described as “flat-out wrong”.
The report said that strikes on the heavily fortified enrichment facilities at Fordo and Natanz had sealed off entrances but failed to destroy underground structures.
Officials familiar with the leaked Defense Intelligence Agency evaluation warned it was an early assessment that could change as more information became available. […]
The preliminary assessment also indicated that some of Iran’s enriched uranium stockpile had been moved prior to the attack.
According to sources familiar with it, Iran’s centrifuges remain largely “intact” with the destruction limited to aboveground buildings.
Entrances to two nuclear facilities were blocked and some infrastructure was damaged, they said, but much of the deeper installations survived the blasts. […]
Tehran has always maintained its nuclear programme was for peaceful purposes.”
“Satellite images reveal new signs of damage at Iranian nuclear sites” Shayan Sardarizadeh and Thomas Spencer (BBC Verify), 25/6/25
“A leaked US intelligence document has cast doubt on the overall impact of the strikes. Media coverage of its conclusions prompted an angry response from President Donald Trump. […]
Israel, and subsequently the US, said strikes were aimed at preventing Iran from building a nuclear weapon. Iran has consistently denied those allegations, insisting its nuclear programme is for peaceful purposes.”
Coverage of that story continued the following day.
“CIA director says Iran’s nuclear sites ‘severely damaged’” Brandon Drenon, 26/6/25
“It comes a day after a leaked preliminary assessment from a Pentagon intelligence agency suggested core components of Iran’s nuclear programme remained intact after the US bombings. […]
A report from the Pentagon’s Defense Intelligence Agency was leaked to US media on Tuesday, estimating that the US bombing had set back Iran’s nuclear programme “only a few months”.
The US defence secretary said that assessment was made with “low confidence”.”
“Hegseth talks up US strikes on Iran in push for public approval” Anthony Zurcher, 26/6/25
Defence Secretary Pete Hegseth took the lectern at the Pentagon briefing room on Thursday morning with two goals.
He wanted to present evidence of the success of the American attack on Iran’s nuclear facilities, pushing back against a preliminary defence intelligence assessment that suggested the strikes were less effective.
And he wanted to berate the American media and paint their coverage of that preliminary report as unpatriotic and disrespectful to the “brave men and women” in the US military. […]
It’s also why his [Trump’s] critics were so eager to boost the preliminary Pentagon report that undercut his claims – and why journalists, attuned to politicians motivated by political advantage, took note.”
Whether or not Zurcher includes his own BBC colleagues in the category of ‘journalists attuned to politicians motivated by political advantage’ is unclear but what is obvious is that no small number of them considered third-hand claims newsworthy simply on the basis of the fact that they had been published by their “partner” CBS or other US media outlets.
Axios reported that the DIA assessment which was the basis for that flurry of BBC reporting had been put together in the 24 hours after the bombings and was based on a review of satellite photos rather than on-the-ground witnesses to the damage, that the report itself acknowledged the “low confidence” of the assessment and that it was of course classified information leaked by parties – and for reasons – currently unknown.
Remarkably, none of those issues – or the fact that the BBC of course had absolutely no way of confirming the claims allegedly made in the assessment – hindered the corporation’s extensive promotion of that story.
