Recent satellite photos show continued activity at a controversial Iranian military site that international weapons inspectors have repeatedly been denied access to, CNN reported Thursday, November 29. According to the Institute for Science and International Study, imagery taken on November 7 shows changes in the roofs on two key buildings at the Parchin Military Complex. ISIS also pointed out there is a new addition on the building suspected of containing a high-explosives chamber and piles of dirt not seen in an image from September 19. ISIS said the imagery indicates additional changes will be made to the site, making it more difficult for the international inspectors. Since January, the IAEA has been seeking access to the site, where it suspects Iran may have conducted high-explosives tests related to the development of nuclear weapons. Iran has refused entry to the IAEA’s inspectors.
