IAEA report: Iran doubled its underground nuclear capacity
UN nuclear watchdog's quarterly report, released Thursday, also says 'extensive activities' are taking place at Iran's Parchin military complex.
Iran has doubled the number of uranium enrichment machines it has in an underground bunker, a UN report said on Thursday, showing Tehran continued to defy Western pressure to stop its atomic work and the threat of Israeli attack.
In the weeks and months when Israeli politicians increased their talk of air strikes on Iran's nuclear sites, the Islamic Republic was rapidly increasing the enrichment capacity of its Fordo site, buried deep underground to withstand any such hit.
The UN International Atomic Energy Agency said in its quarterly report on Iran that the number of centrifuges at Fordo, near the holy Shi'ite Muslim city of Qom, about 130 km (80 miles) from Tehran, had more than doubled to 2,140 from 1,064 in May.
The new machines were not yet operating, it said.
Iran's supreme leader repeated this week that Iran's nuclear program was entirely peaceful. "Our motto is nuclear energy for all and nuclear weapons for none," Ayatollah Ali Khamenei told a developing nations summit in Tehran.
But the expansion in enrichment infrastructure and the increasing in stockpiles of potent nuclear material revealed in the report will do nothing to allay fears or reduce the diplomatic and sanctions pressure on Iran.
The report showed that Iran had produced nearly 190 kg (418 pounds) of higher-grade enriched uranium since 2010, up from 145 kg in May.
Iran says it needs this material - which is much purer than fuel needed for electricity generation - for a medical research reactor, but it also takes it significantly closer to making potential bomb material.
The IAEA also expressed concerns about Parchin, a military site south of the capital that it wants to inspect for evidence of past nuclear weapons development.
"Significant ground scraping and landscaping have been undertaken over an extensive area at and around the location," it said.
Five buildings had been demolished and power lines, fences and paved roads removed, the report said, "extensive activities" that would hamper its investigation if granted access.
"The activities observed ... further strengthen the agency's assessment that it is necessary to have access to the location at Parchin without further delay", the IAEA said.
Iran says Parchin is a conventional military facility and has dismissed the allegations about it as "ridiculous".
Foreign Minister Ali Akbar Salehi, meeting UNSecretary-General Ban Ki-moon in Tehran on Thursday, was quoted by Iranian state TV as saying: "The West has put sanctions on Iran for years, however the Iranian nation continues to resist and make progress."
A Western diplomat said the doubling of enrichment capacity at Fordo was a "worrying trend" showing that Tehran continued to expand its program.
