A report released Wednesday by the Institute for Science and International Security (ISIS) revealed “considerable sanitization and earth displacement activity” at the Parchin military site in Iran, a sign of a potential nuclear cover-up there.

“The entire area surrounding the buildings [in Parchin] appears to have been bulldozed, covered, and flattened,” the report said. “The only remaining traces of activity are the apparent base of one of the demolished buildings and earth piles formed as a result of earth removal and displacement.”
