Two days ago FOX News ran another sensational story about Iran's nuclear program.
Satellite images of Iran nuclear site raise alarms as IAEA meets in Vienna
However the claims in that story are based on a report by David Albright's Institute for Science and International Security (ISIS). Albright is known for his false or misleading conclusions about mostly random 'evidence'.
The story:
Fox News has obtained new satellite images that show unusual activity at Iran’s Sanjarian site, which has been exposed in the past as a suspected manufacturing site for "shock wave generators" – devices which would allow Iran to miniaturize a nuclear weapon.
The new images obtained from Maxar show 18 vehicles at the site on October 15, 2020, more vehicles and excavation in January along with a new access road that was later covered up in March of this year. All that is visible by satellite now are excavation swirls and new trenches, according to analysis from Itay Bar Lev of The Intel Lab who worked in conjunction with the Institute for Science and International Security.
The site, which is 25 miles outside Tehran and has a population of 361, was first revealed when Israel's Mossad obtained Iran's secret nuclear archive in 2018: 50,000 computer files and 50,000 documents outlining Iran's Amad project, the scientific program to build a nuclear weapon which the IAEA says was halted in 2003.
The pictures FOX News presents are supposed to show the site on October 15 2020 and on January 18 2021. There are only slight differences.

Remarks on the pictures note that there are "18 vehicles", "concealment sheeting" and "bulldozer scarring". How those are supposed to be related to alleged manufacturing of "shock wave generators" for nuclear weapons is beyond me.
The Times of Israel adds some quotes:
According to the institute, also known as ISIS, the nuclear archive smuggled out of Iran by Israel’s Mossad spy agency in 2018 contained information about Sanjarian’s role in plans to produce shockwave generators, which are key components in the miniaturization of nuclear weapons.
…
Apparently following that development, activities renewed at the Sanjarian site in October 2020, where excavations continued until January 2021, according to the ISIS.“The burial site was reopened, but placed under a white sheeting that covered the excavated area, concealing what’s underneath from outside observers, including satellites,” it said Wednesday. “Less than two months later, the area appeared abandoned, with only empty trenches left behind. Then in just the past month, the area was bulldozed and graded over, like nothing ever happened [t]here.”
…
The insinuation appeared to be that Iran, spooked by the IAEA inspecting previously unknown nuclear sites using information obtained by the Mossad, has allegedly attempted to cover up any incriminating evidence from the Sanjarian compound.
There is a history of such insinuation by David Albright's ISIS. The ones in 2008 about an alleged North Korean reactor in Syria turned out to be false. In 2013 Albright's ISIS issued a report about alleged Iranian imports of magnets which, ISIS claimed, were for Uranium centrifuges. There was only one problem with that claims. The magnets Iran allegedly ordered would not have fit for that purpose. In 2015 Albright was very concerned about a massive nuclear explosion chamber in an Iranian building which was covered with a pink(!) tarp. Several media reported about it. When finally people went there they found the building empty.
It is therefore not astonishing that the most recent claims about the Sanjarian (Jajrud) site also turn out to be false.

Iran Nuclear Program: What do the satellite images of Jajrud show?
Short answer: The filming scene of the series "Nun Kh"Recently the team @TheIntelLab in collaboration with the team @TheGoodISIS have published satellite images of Sanjarian village.
2 / They claimed that they have observed excavations 100 meters away from the Sanjarian site. These activities took place between the fall of last year and the spring of this year. Satellite images show parked cars. In addition to leveling the ground, surface excavation and covering the excavated surface.
3 / The behind-the-scenes film of the series "Nun Kh", which was apparently broadcast during the Eid holidays, shows that the filming took place at exactly the same point between autumn and spring. And these changes are nothing but logistics and filming scenes.

The location pictures shown in the video are consistent with the satellite pictures. The TV series production time frame fits exactly with the rearranged dirt.

A production company finds a fitting location for its TV series. Satellite pictures show that some dirt was moved around. "Nuclear, nuclear, something," screams David Albright. The usual media report the nonsense.
One wonders how long it will take Fox News to issue a correction for this one.
