In the latest episode of Photo Evidence, host Catherine Barnwell pores over years of satellite images of Iran's Taleghan 2 military facility, one of the suspected homes of the Islamic Republic's nuclear weapons programme.
asserted
Barnwell → pore → programme
Taleghan 2 sits inside the vast Parchin military complex, around 20 miles southeast of Tehran.
asserted
Taleghan → sit → Tehran
The complex has been repeatedly bombed since 2024.
asserted
complex → bomb → 2024
The facility was built in the early 2000s as part of the infamous Amad Plan, Iran's secret programme to develop a nuclear warhead.
asserted
facility → build → warhead
Tehran has always denied the plan existed.
asserted
plan → deny → ?
Under Barack Obama's 2015 nuclear deal, Iran agreed to a ban on exactly this kind of weapons research.
asserted
Iran → agree → research
But that deal has since collapsed, and satellite images taken since 2024 have captured a string of strange developments at Taleghan 2.
asserted
images → collapse → Taleghan
Israel flattened the building in October 2024.
asserted
Israel → flatten → October
Iran rebuilt it and buried the new bunker under concrete and earth, only for Israel to strike it again in March 2026.
asserted
Israel → rebuild → March
Barnwell shows how Iran is rebuilding the facility once again, and speculates on what the Islamic Republic could be hiding inside.

Satellite imagery showed Iran beginning repair work at the site,' she explained.
asserted
she → show → site
'Iran erected a massive tarpaulin canopy over the entire damaged buried structure, completely obscuring the work taking place beneath it from aerial and satellite observation.
asserted
Iran → erect → observation
'Presumably, this is intended to conceal what is happening beneath it, including the potential movement of new testing equipment back into the facility.
asserted
what → intend → facility
One of the biggest questions is whether Iran is replacing the high explosive containment vessel believed to have been destroyed in the March strikes.
asserted
Iran → replace → strikes
'In 2018, when Israel's Mossad seized Iran's secret nuclear archive, the documents and photographs recovered included evidence relating directly to Taleghan 2 in 2003.
asserted
documents → seize → 2003
One of the most significant pieces of equipment documented in the archive was a small cylindrical steel vessel installed inside Taleghan 2 to contain high explosive experiments.
asserted
One → document → experiments
The vessel was used for what are known as cold tests.
asserted
what → use → tests
In these experiments, scientists use conventional explosives to compress uranium proxies, allowing scientists to study the mechanics of a nuclear implosion without triggering a nuclear explosion.
asserted
scientists → use → explosion
It is the mandatory final step to engineering a functional nuclear warhead.'
asserted
It → engineer → warhead
Not only does Barnwell's research pose troubling questions about Iran's current designs on a nuclear weapon, but it also suggests the Middle Eastern nation was conducting nuclear weapons research despite commitments to the contrary.
uncertain
nation → pose → contrary
That same archive revealed that Iran never truly scrapped its programme, with leaders ordering the work split up and hidden in 2003.
asserted
leaders → reveal → 2003
'The files revealed that Taleghan 2 was never fully abandoned after 2003, and that experiments on nuclear explosives had continued under tighter secrecy throughout the 2000s and 2010s,' Barnwell explained.
asserted
Barnwell → reveal → 2000s
'Crucially, the archive exposed that in mid 2003, Iranian leadership ordered the programme to be divided rather than destroyed.
asserted
programme → expose → 2003
They quietly moved the sensitive research into a covert track, dispersing scientists across universities and front organisations so the dual-use data generated at places like Taleghan could keep moving forward under academic cover.
uncertain
data → move → cover
However, in the months leading up to 2024, intelligence declassifications showed that Iran took that expertise off ice, quietly returning to the undeclared Taleghan 2 facility to resume top-secret active explosive research.'
