"There are visible tracks made by heavy machinery used in the demolition process," said a commentary by the think tank accompanying the photos. "Heavy machinery tracks and extensive evidence of earth displacement is also visible throughout the interior as well as the exterior of the site's perimeter."
"We have the general concern that these activities may hamper our future verification activities," at the site, [Amano] said. "Information that we have indicates that activities may have been undertaken related to the development of nuclear explosive devices and ... having access is very important to clarify this issue."
Amano announced last month that an "agreement was at hand" on the IAEA's request to visit sites where it suspects Iran might have developed nuclear weapons. His remarks today indicate that the announcement might have been "premature" and will reinforce the beliefs of those who say the nuclear negotiations process is merely a pretense that Iran is using to buy time to hide evidence of nuclear work until it can no longer hold off the IAEA, the NYT reports.
