VIENNA (AP) — The U.N. atomic agency has found evidence at an underground bunker in Iran that could mean the country has moved closer to producing the uranium threshold needed to arm nuclear missiles, diplomats said Friday.

The news comes a day after Iran and six world powers found they were still far apart over how to oversee Tehran's atomic program but wanted talks to continue to avoid possible military action.

Iran is under several rounds of U.N. sanctions for its failure to disclose information on its controversial nuclear program. Tehran says it is enriching uranium to provide more nuclear energy for its growing population, while the U.S. and other nations fear that Iran doing that so it can later make nuclear weapons.

The International Atomic Energy Agency has found traces of uranium enriched up to 27 percent at the Fordo enrichment plant in central Iran, several diplomats told The Associated Press.

That is still substantially below the 90-percent level needed to make the fissile core of nuclear arms. But it is above Iran's highest-known enrichment grade, which is close to 20 percent and can be turned into weapons-grade material much more quickly than the Islamic Republic's main stockpile, which can only be used for fuel at around 3.5 percent enrichment.

Calls to Ali Asghar Soltanieh, Iran's chief delegate to the IAEA, were rejected and the switchboard at the Iranian mission said he was not available. IAEA media officials said the agency had no comment on the latest report.

The diplomats — who demanded anonymity because their information is privileged — said the find did not necessarily mean that Iran was covertly raising its enrichment threshold toward weapons-grade level. They said the centrifuges that produce enriched uranium could have over-enriched at the start as technicians adjusted their output — an assessment shared by nonproliferation expert David Albright.

Albright, whose Washington-based Institute for Science and International Security looks for signs of proliferation, said a new configuration at Fordo means its tends to "overshoot 20 percent" at the start.

"Nonetheless, embarrassing for Iran," he wrote in an email to the AP.

The latest attempt to persuade Iran to compromise and let U.N. experts view its nuclear program ended inconclusively Thursday at a meeting in Baghdad. At the talks, six nations — the United States, Russia, China, Britain, France and Germany — failed to persuade Tehran to freeze its 20 percent enrichment. Envoys said the group will meet again next month in Moscow.

Iran went into the Baghdad talks urging the West to scale back on recently toughened sanctions, which have targeted Iran's critical oil exports and have effectively blackballed the country from international banking networks. The 27-nation European Union is set to ban all Iranian fuel imports on July 1, shutting the door on about 18 percent of Iran's market.

Iran started enriching uranium to 20 percent last year, mostly at Fordo, saying it needed the material to fuel a research reactor and for medical purposes. Still, its long-standing refusal to stop enrichment and accept reactor fuel from abroad has sparked fears it wants to expand its domestic program to be able to turn it toward making weapons.

Those concerns have increased since it started higher enrichment at Fordo, which is carved into a mountain to make it impervious to attack from Israel or the United States. Those two nations have not ruled out using force as a last option if diplomacy fails to curb the Islamic Republic's nuclear program.

Saeed Jalili, Iran's top nuclear negotiator, offered a lukewarm assessment of the latest negotiations, in light of European and American refusal to lift tough sanctions against Iran as Tehran had hoped.

"The result of the talks was that we were able to get more familiar with the views of each other," Jalili told reporters.

European diplomats focused on the positives.

"It is clear that we both want to make progress and that there is some common ground," European Union foreign policy chief Catherine Ashton, who led the Baghdad talks, told reporters. "However, significant differences remain. Nonetheless, we do agree on the need for further discussion to expand that common ground."

But in Washington, Secretary of State Hillary Rodham Clinton said significant differences remain between the two sides and that it's now up to Iran "to close the gaps."

"Iran now has the choice to make: Will it meet its international obligations and give the world confidence about its intentions or not?" Clinton said.

The diplomats who spoke to the AP said a confidential IAEA report on Iran's nuclear program to be released later Friday to the agency's 35-nation board will mention of the traces of 27-percent enrichment found at Fordo.

Iran already has around 700 centrifuges churning out 20-percent enriched uranium at Fordo. The diplomats said the report will also note that — while Iran has set up around 350 more centrifuges since late last year at the site — these machines are not enriching.

While the reason for that could be purely technical, it could also be a signal from Tehran that it is waiting for progress in the negotiations.

The report is also expected to detail the state of talks between the U.N. nuclear agency and Iran that the agency hopes will re-launch a long-stalled probe into suspicions that Tehran has worked on nuclear-weapons related experiments — charges that Tehran denies.
