VIENNA (Reuters) - Iran has sharply stepped up its controversial uranium enrichment drive, the U.N. nuclear agency said on Friday in a report that will further inflame Israeli fears the Islamic Republic is pushing ahead with atomic bomb plans.

The nuclear watchdog also gave details of its mission to Tehran this week where Iran failed to respond to allegations of research relevant to developing nuclear arms - a blow to the possible resumption of diplomatic talks that could help calm worries about a new war in the Middle East.

"The Agency continues to have serious concerns regarding possible military dimensions to Iran's nuclear program," the International Atomic Energy Agency said in a quarterly report about Iran issued to member states.

Iran's increase of work that can have both civilian and military purposes underlines that it has no intention of backing down in a long-running dispute with the West that has sparked fears of war.

U.S. crude futures extended a rally on the IAEA's findings, which added to concerns that Iran's tensions with the West would escalate. It gained more than $2 to hit the highest intraday price in nine months.

The White House said the IAEA report confirmed that Iran was violating U.N. Security Council resolutions with its nuclear enrichment program.

"When combined with its continued stonewalling of international inspectors, Iran's actions demonstrate why Iran has failed to convince the international community that its nuclear program is peaceful," White House National Security Council spokesman Tommy Vietor said in a statement.

In what would be a big expansion, Iran has increased the number of centrifuge machines enriching uranium - material that can be used to make atomic bombs if refined much further - by well over a third since late last year, the report indicated.

Preparatory work to install thousands more centrifuges is under way, potentially shortening the time needed to make high-grade uranium for nuclear weapons.

Tehran says its nuclear program is exclusively for civilian purposes, but its refusal to curb enrichment has drawn increasingly tough sanctions on its oil exports.

Iran's ambassador to the IAEA said the report had vindicated its position and insisted Tehran had no intention of giving up its nuclear march.

"The IAEA report indicated that all Iran's nuclear activities are under the supervision of the agency," the semi-official Fars news agency quoted Ali Asghar Soltanieh as saying.

"It shows again that Iran's nuclear activity is peaceful."


Israel, which has threatened Iran with pre-emptive strikes on its nuclear sites, had no immediate comment.

Israeli Defence Minister Ehud Barak has warned that the Islamic state's nuclear research could soon pass into what he called a "zone of immunity," protected from outside disruption.

The European Union's foreign policy chief, Catherine Ashton, said the IAEA report increased concerns over the real purpose of Iran's nuclear program.

Ashton, who represents the United States, Russia, China, Germany, France and Britain in stalled talks with Iran, also urged Tehran to cooperate fully with the IAEA.

"The findings of this new IAEA report contribute to further increased concerns on the exclusively peaceful nature of the Iranian nuclear program," Ashton's spokeswoman said.

"Iran has to address all existing concerns and to build confidence in the nature of its nuclear program."

The confidential IAEA report showed that Iran since last November had tripled monthly output of uranium refined to a level that brings it significantly closer to potential bomb material, an official familiar with the agency's probe said.

"The concern is that they are trying to give the impression that they are putting in the capability that could much more quickly make weapon-grade uranium," nuclear proliferation expert David Albright said.

"This could all be posturing to show further defiance, but unfortunately it does concern many countries about what is Iran planning." Albright added that Iran seemed to have problems developing newer and more efficient centrifuges.


The failure of the two-day IAEA visit to Tehran this week could hamper any resumption of wider nuclear negotiations between Iran and the six world powers as the sense grows that Tehran feels it is being backed into a corner.

The IAEA team sought answers from Iran raised by a previous agency report in November that suggested it had pursued military nuclear technology. Those findings helped to precipitate the latest sanctions by the EU and United States.

Making clear the two sides had been far apart, the IAEA report said there were major differences on how to tackle the issue and that Iran had dismissed the U.N. agency's concerns as "unfounded." No further meetings are planned.

IAEA Director General Yukiya Amano urged Iran in the report to provide "early access" to Parchin, a military site near Tehran seen as central to the agency's investigations into possible military aspects of Iran's nuclear work.

His agency's report showed Iran had carried out an expansion of activities both at its main enrichment plant near the central city of Natanz and at the Fordow underground site.

Enriched uranium can be used to fuel nuclear power plants, which is Iran's stated aim, or provide material for bombs if refined much further, which the West suspects is Tehran's ultimate plan.

At Natanz, the IAEA report said Iran had declared that 52 cascades - each containing about 170 centrifuges - were now operating, up from 37 in November. At Fordow, about 700 centrifuges are now refining uranium to a fissile concentration of 20 percent and preparations are under way to install more.

Fordow is of particular concern for the West and Israel as Iran is shifting the most sensitive aspect of its nuclear work, 20 percent enrichment, to the site.

Estimated to be buried beneath 80 meters (265 feet) of rock and soil, it gives Iran better protection against any Israeli or U.S. military strikes.

Nuclear bombs require uranium enriched to 90 percent, but Western experts say much of the effort required to get there is already achieved once it reaches 20 percent concentration, shortening the time needed for any nuclear weapons "break-out."

The IAEA said Iran had now produced nearly 110 kg (240 pounds) of uranium enriched to 20 percent since early 2010. Western experts say about 250 kg (550 pounds) are needed for a nuclear weapon, although it would need to be enriched much further.

So giving the international inspectors full access to their facilities is called “stonewalling” in America. Does the government think we’re all idiots? The Warhawks are rattling their sabres because already they thirst for more war, and more war profits being sucked out of the American taxpayer. I have no doubt Amadinijad is complicit in this charade that they’re pulling on the people of America and Israel to justify more war at the cost of American dollars and Iranian lives.

The American people need to stand up to their Government. The war in Afghanistan is the biggest draw on American tax dollars, and the warhawks want to double that amount with a new war, and more! Tell the government that America has had enough war, and to leave Iran alone. There’s still no proof that Iran is creating nuclear weapons; even secretary of defence Leon Panetta has said, on the record, that Iran isn’t trying to get nuclear weapons, so what more does it take to get people to listen to the truth?

We’re all worried that a preemptive strike by Israel on Iran’s nuclear weapon facilities will bring the US into a regional war.

So would a nuclear attack on Israel.

Take your pick. The religious leader who is also the political leader of Iran wants a war and will stop at nothing to get one.

The reason, of course, that they needed 20% enriched uranium was for their research/medical reactor in Tehran. The West/US first supported a deal to be brokered by Turkey and Brazil to replenish the 20% uranium, necessary to fulfill Iranian medical requirements. But when Turkey and Brazil came up with the deal, the US stupidly spurned it. I say stupidly, assuming that they really care about Iran’s nuclear program. The alternative, probably more likely, is they simply want to go to war with Iran, to destroy another country that insists on its own sovereignty.

This is just more evidence that we have become a sham democracy, run by a bunch of power hungry hegemonists. The people of America look like cannon fodder and and dupes for shake-down artists.
