High-resolution satellite images from VANTOR Technologies taken in September and October 2026 showed significant renewed activity at Min-Zadayi, a nuclear weapons development facility in northeastern Tehran that was exposed and attacked by Israel during Operation 'Roar of the Lion.' Several buildings, as well as underground structures, were reportedly destroyed in the strike. This was published in the journal of the Institute for Science and International Security. The latest satellite images indicated a return to regular vehicle movement around the site, following an extensive cleanup operation that included removal of debris and waste and repair of damage to the hillside slope. In one of the areas attacked in March 2026, ongoing earthworks activity is visible.
