IAEA, Iran Fail to Reach Deal at Nuclear Talks in Vienna

Talks between the UN atomic energy agency and an Iranian delegation failed to strike deal resolving concern over Iran's nuclear program; senior UN official said no further talks were scheduled.

The UN nuclear watchdog and Iran failed on Friday to strike a deal aimed at allaying concerns about suspected nuclear weapons research by Tehran, a setback in efforts to resolve the stand-off diplomatically before any Israeli or U.S. military action.

A flurry of bellicose rhetoric from some Israeli politicians this month has fanned speculation that Israel might hit Iran's nuclear sites before the U.S. presidential election in November.

Tensions rose another notch on the eve of Friday's talks between Iran and the International Atomic Energy Agency (IAEA) when diplomatic sources said Iran had installed many more uranium enrichment centrifuges at its Fordo underground site.

While the new machines are not yet operating, the move reaffirmed Iranian defiance of international demands on it to suspend enrichment and may strengthen the Israeli belief that toughened sanctions and concerted diplomacy are failing to make the Islamic Republic change course.

"The discussions today were intensive but important differences remain between Iran and the UN that prevented agreement," Herman Nackaerts, the International Atomic Energy Agency's chief inspector, told journalists after about seven hours of talks with an Iranian delegation in Vienna.

"At the moment we have no plans for another meeting."

Little headway appeared to have been made on the IAEA's most urgent request - access for its inspectors to the Parchin military site where the IAEA believes Iran has done explosives tests relevant for developing a nuclear weapons capability.
Iran's ambassador to the Vienna-based IAEA, Ali Asghar Soltanieh, said that "undoubtedly some progress" was made but that differences remained.

"Because it is a very complex issue ... issues related to national security of a member state are something very delicate," the veteran Iranian diplomat said.
"But I have to say that we are moving forward ... and we are going to continue this process so that we at the end of the day will have a framework agreed by both sides."

Soltanieh had said before the talks began: "Both sides are trying to bridge the gap."

The diplomatic sources who revealed the expansion of centrifuge capacity at Fordo also said satellite imagery indicated Iran had used a brightly coloured tent-like structure to cover a building at Parchin, increasing concern about a possible removal of evidence of illicit past nuclear work there.

Earlier on Friday, Israel signalled its patience with diplomacy was fading.

"Only yesterday we received additional proof that Iran is continuing accelerated progress towards achieving nuclear weapons and is totally ignoring international demands," Prime Minister Benjamin Netanyahu said before the talks ended.

Asked about the outcome of the Vienna meeting, a Western diplomat accredited to the IAEA said: "As dismal as expected."

A U.S. State Department official, asked about the revelation of more enrichment capacity at Iran's Fordo plant, said world powers would keep using diplomacy and sanctions to press Iran into nuclear restraint, but time was running out.

"We and our (big power) partners remain strongly committed to keeping a nuclear weapon out of the hands of the Iranian regime, The window of opportunity to resolve this diplomatically is open, but is rapidly closing," he said.

Iran, the world's No. 5 oil exporter, says it wants nuclear energy for more electricity to serve a rapidly growing population, not nuclear weapons, and has threatened wide-ranging reprisals if attacked.

Nackaerts, the IAEA's global chief of inspections, said before the meeting that the broader goal was a deal on greater, overall inspector access to answer the UN watchdog's questions about possible military dimensions to Iran's nuclear program.

It was the first meeting between the two sides since discussions in early June petered out inconclusively, dashing previous hopes that an accord might be on the cards.

Friday's talks were separate from Tehran's negotiations with six world powers that have made little headway since resuming in April after a 15-month hiatus, but the focus on suspicions about Iran's nuclear ambitions mean they are still closely linked.

Washington has said there is still time for diplomatic pressure to work in making Iran curb its enrichment program, which is the immediate priority of the six powers - the United States, Britain, Russia, China, France and Germany.

Refined uranium can fuel nuclear power plants or nuclear bombs, depending on the level of enrichment.
