VIENNA - Iran has been hauling dirt to a site that international nuclear experts want to inspect, Western diplomats said on Wednesday, saying the findings were based on satellite images and they reinforced suspicions of a clean-up.

They said the pictures, presented during a closed-door briefing for member states of the International Atomic Energy Agency (IAEA), suggested Iran was continuing to try to hide incriminating traces of any illicit nuclear-related activity.

The allegations come a few days after the IAEA said in a report on Iran's nuclear program that "extensive activities" undertaken at the Parchin site since early this year would seriously undermine its investigation, if and when inspectors were allowed access.
