New satellite photos show activity at Iranian nuclear site bombed by ‘Israel’

New satellite imagery reveals significant renewed activity at Iran’s Minzadayi nuclear weapons development compound northeast of Tehran, a site ‘Israel’ struck earlier this year, according to a report by the Institute for Science and International Security (ISIS).

High-resolution images from VANTOR Technologies, dated September and early October, show a return to regular vehicle traffic at the heavily secured facility after an extensive cleanup.

Rubble and debris from the March 3 ‘Israeli’ attack have been cleared, hillside damage has been repaired, and earth-moving work continues at a surface area designed to resemble a courtyard where multiple craters appeared after the strikes.

Cars are parked outside the security perimeter, while passenger vehicles and trucks operate inside.

NEW Report: Significant Activity Identified at Minzadayi, an Iranian Nuclear Weapons Development Site High resolution @vantortech satellite imagery from September and October 2026 shows significant renewed activity at Minzadayi, a nuclear weapons development compound northeast of Tehran revealed by Israel during the 2026 war. The compound was attacked by Israel on March 3rd, 2026, destroying several buildings and likely underground structures. The recent satellite imagery indicates a return to regular vehicle activity around the site post extensive cleanup operation that included the clearing of rubble and debris and repair of damage on the hillside. One area attacked in March 2026 shows ongoing earth moving activity. The earth moving activity is occurring at a surface made to look like a courtyard where multiple craters could be seen following the attacks on the site in March 2026. Significant vehicle presence can be seen throughout the site between early September and early October 2026. Cars are parked outside the security perimeter in the parking lot, and many passenger vehicles and trucks can be seen inside the perimeter. Given what is known about this compound, this activity may be indicative of an effort by Iran to reestablish a nuclear weapons development capability and to reconstitute what was lost in the attack on the compound. Based on public reporting and statements released by the IDF, the nuclear weapons work carried out here likely involved research and development on nuclear warheads. The IDF originally stated, that a “group of nuclear scientists operated covertly to develop a key component in the nuclear weapons system,” adding that “the complex is designed to enable the restoration of the required technology and the advancement of capabilities for the development of nuclear weapons.” @IntelliTimes, released additional information on the compound. In a post from September 24, 2026, it states that the nuclear weapons related infrastructure was established in 2022 and “absorbed part of the means from the nuclear warehouse,” a common reference to the Turquz Abad site revealed by Israeli Prime Minister Benjamin Netanyahu in September 2018. Netanyahu revealed the site following Iran’s removal of more than a dozen shipping containers from the site that were assessed to hold nuclear material and equipment relevant to Iran’s nuclear weapons capabilities.[4] When the IAEA visited Turquz Abad in March 2019, it found evidence that nuclear material or contaminated equipment had been present at the site and the IAEA Board has since been pressing Iran to answer the IAEA’s questions about the current whereabouts of said material and/or equipment. @IntelliTimes indicates Iran did not simply move the material and/or equipment to a new long term storage site but used the new site in northeast Tehran, aka Minzadayi, to establish an” industrial nuclear headquarters for the reconstruction of research, development, and adaptation infrastructure for nuclear warheads,” including the means to “produce cores of enriched uranium and the explosive material required to cast into them the detonation chain.”[5] The current renewed effort underway at this highly secure compound suggests that the work being conducted here is of top priority.

The compound, also referred to as Minzadehei or Min-Zadayi, was revealed by ‘Israel’ during the 2026 conflict as a partially underground site where nuclear scientists worked on weapons-related research.

The ‘Israeli’ military stated at the time that a “group of nuclear scientists operated covertly to develop a key component in the nuclear weapons system” and that “the complex is designed to enable the restoration of the required technology and the advancement of capabilities for the development of nuclear weapons.”

The March attack destroyed several buildings and likely damaged underground structures.

ISIS analysts warn that the latest activity raises serious concerns.

“Given what is known about this compound, this activity may be indicative of an effort by Iran to reestablish a nuclear weapons development capability and to reconstitute what was lost in the attack on the compound,” the report states.

The think tank notes that the work previously conducted there likely focused on research and development of nuclear warheads.

Open-source reporting cited by ISIS links the site’s origins to 2022, when it reportedly absorbed materials and equipment from the Turquz Abad “atomic warehouse” that ‘Israeli’ Prime Minister Benjamin Netanyahu publicly exposed in 2018.

One assessment describes Minzadayi as an “industrial nuclear headquarters for the reconstruction of research, development, and adaptation infrastructure for nuclear warheads,” including capabilities to produce enriched uranium cores and related explosive materials.

The renewed operations at this high-security location suggest the effort remains a priority for Tehran.
The findings come amid broader monitoring of Iranian nuclear-related sites following the 2025 and 2026 military campaigns.

While Iran has consistently maintained that its nuclear program is peaceful, the combination of cleanup, earth-moving, and sustained vehicle presence at a facility previously tied to weapons work has drawn close scrutiny from nonproliferation experts.
