The Parchin complex is at the centre of Western suspicions that Iran is developing atom bombs despite Tehran's repeated denials
of any such ambition. A report from the International Atomic Energy Agency (IAEA) last week said satellite images showed "extensive activities" at Parchin.
Iranian officials have refused access to the complex, southeast of Tehran, saying it is a military
"The reasons and document have still not been presented by the agency to convince us to give permission for this visit," the head of the Atomic Energy Organization of
Iran, Fereydoun Abbasi-Davani, was quoted as saying by Fars news agency on Saturday.
Six world powers failed to convince Iran last week to halt its most sensitive nuclear work, but they will
meet again in Moscow next month to try to end a standoff that has raised fears of a new war that could threaten global oil supplies.
Last November, an IAEA report found that Iran had built a large containment vessel in 2000 at Parchin in
which to conduct tests that the agency said were "strong indicators of possible weapon development."
In last week's report, the IAEA did not elaborate on what activities it believed were happening there, but
Western diplomats suspect Iran is trying to remove any potentially incriminating evidence. Tehran rejects this charge.
After a visit to Tehran last week, IAEA chief Yukiya Amano said he was close to an agreement with Iran on
inspection visits to nuclear facilities but some differences remained.
The US-based Institute for Science and International Security thinktank has said there is concern Iran may
be trying to cleanse the building at Parchin - possibly by grinding down surfaces, collecting the dust and washing the area thoroughly.
IAEA Director General Yukiya Amano is a no-nonsense Japanese national who has overturned the Mohammed
ElBaradei regime that virtually enabled Iran to work toward building
a bomb during his tenure. His hands are somewhat tied by procedure
and international law, but he has shown a much healthier skepticism of Iran's program. This has been reflected in recent IAEA reports that sound more definitive regarding Iran's push to build a
But IAEA inspections are still dependent on a host country cooperating. We probably won't find out what Iran
was doing at Parchin as long as the Iranians can scrub the site prior to any action by the nuclear watchdog agency.
