Iran, U.S. trade blame over failed nuclear deal

DUBAI, United Arab Emirates -- Iran and the United States on Monday blamed each other for the failure to reach agreement on a deal to limit Iran's uranium enrichment in exchange for an easing of Western sanctions.

In spite of the accusations, there was some diplomatic progress as Iran promised to offer more information and expanded access to U.N. nuclear inspectors -- including more openings at a planned reactor and uranium site.

U.S. Secretary of State John Kerry said Iranian envoys had backed away from a wider deal this weekend seeking to ease Western concerns that Tehran could one day develop atomic weapons.

Iran's foreign minister, Mohammad Javad Zarif, countered by criticizing Kerry's remarks, telling an Iranian TV talk show that the American's "conflicting statements" damaged confidence in the process, adding that "considerable progress was made" in Geneva.

The flurry of announcements and comments showed both the complexities and urgency in trying to move ahead on an accord between Iran and world powers after the talks in Geneva failed to produce a deal.

With negotiators set to resume next week, Iranian officials promoted a separate pact reached with the U.N. nuclear chief Yukiya Amano as a "roadmap" for greater cooperation and transparency, which could move the talks ahead. But the plans do not mention some of the sites most sought by U.N. teams to probe suspicions of nuclear-related work, notably the Parchin military facility outside Tehran.

"It's an important step forward, but by no means the end of the process," Amano said in Tehran. "There is still much work to be done."

Western leaders, meanwhile, were keen to display a unified front after reports that France had broken ranks in Geneva and demanded more concessions from Iran on enrichment levels and an under-construction heavy water reactor that produced a greater amount of plutonium byproduct, which could be used in eventual weapons production. Kerry said it was Iran that put the brakes on reaching a first-phase agreement, but gave no details on the Iranian concerns and suggested it was only a matter of time before a formula is found.

"There was unity but Iran couldn't take it," Kerry said during a stop in Abu Dhabi. He added: "The French signed off on it, we signed off on it."

Kerry told the BBC on Monday that negotiators had been "very, very close ... extremely close" to reaching a deal with Iran.

"I think we were separated by four or five different formulations of a particular concept," he said.

In the BBC interview, Kerry acknowledged "the French have been more vocal about one thing or another." But he said, "the fact is that we had a unity on Saturday in a proposal put in front of the Iranians. But because of some the changes they felt they had to go back and change it."

Later Monday, Zarif criticized Kerry's remarks that blamed Iran for lack of a deal when asked about them on an Iranian TV talk show.

"Conflicting statements harm the credibility of the one who keeps changing positions and damages confidence. The goal of dialogue is to reduce the lack of trust. Conflicting talk doesn't give credit to the person saying it," Zarif said.

He said "considerable progress" was made during three days of talks in Geneva but claimed that most of the hours were spent with the U.S., Russia, China, Britain, France and Germany trying "to resolve differences among themselves." He said he's still hopeful a deal will be reached, but insisted any agreement must include the lifting of all Western sanctions against Iran.

British Foreign Secretary William Hague said the world powers presented a united front to Iran at the weekend talks that failed to reach an accord, and although "some gaps" remained between parties at the talks, "most of those gaps are narrow."

In Jerusalem, Israeli Prime Minister Benjamin Netanyahu has acknowledged that an overall deal is likely between Iran and world powers, which would undercut Israeli threats to launch military action against Iranian nuclear sites. Yet he hailed the delay as a chance to "achieve a much better deal."

"The target date for this deal is the date on which a good deal will be achieved that will deny Iran a military nuclear capability," he told Israel's parliament Monday.

For Netanyahu and his backers, however, hopes have all but evaporated that Iran can be forced by negotiators to completely end its ability to make nuclear fuel. It's now unclear what type of deal would satisfy Israel, which sees a nuclear-armed Iran as a threat to its existence.

Iran has denied it seeks nuclear arms and insists its only seeks reactors for energy and medical applications. Iranian officials portrayed the expanded U.N. access as further sign it seeks to work with the West.

Under the plans, announced at a joint news conference, Iran would allow inspectors a first-time visit of its key Gachin uranium mine on the Gulf Coast and give broader access to the heavy water facility being built in the central city of Arak. Heavy water reactors use a different type of coolant to produce a greater amount of plutonium byproduct than conventional reactors. Inspectors from the U.N.'s International Atomic Energy Agency have already visited the reactor site but seek more extensive examinations.

Plutonium can be used in nuclear weapons production, but separating it from the reactor byproducts requires a special technology that Iran does not possess.

The new accord with the U.N. also calls on Iran to provide more details on its nuclear program including proposed new reactor sites and all planned research reactors. This is important because such facilities use 20 percent enriched uranium, which is the highest level acknowledged by Iran and a key aspect of the ongoing nuclear talks. Halting the 20 percent enrichment -- which is several steps away from weapons-grade -- is a key goal of Western envoys, for which they may offer Iran a possible easing of U.S.-led sanctions.

IAEA teams have combed Iran for years and have around-the-clock monitoring systems at main sites such as the Russian-built reactor at Bushehr on the Gulf Coast and the biggest enrichment facility at Natanz in central Iran. Inspectors also have visited a once-secret enrichment lab, known as Fordo, built into a mountainside south of Tehran after it was disclosed in 2009.

But some areas remain off-limits despite repeated demands from the IAEA.
