Iran nuclear talks extended after deadline passes without deal

Iran and six powers failed for a second time this year on Monday to resolve their 12-year dispute over Tehran's nuclear ambitions and gave themselves seven more months to overcome the deadlock that has prevented them from clinching a historic deal.

Western officials said they were aiming to secure an agreement on the substance of a final accord by March but that more time would be needed to reach a consensus on the all-important technical details.

“We have had to conclude it is not possible to get to an agreement by the deadline that was set for today and therefore we will extend the JPOA to June 30, 2015,” British Foreign Secretary Philip Hammond told reporters at the end of the talks.

He was referring to the so-called Joint Plan of Action, an interim deal agreed between the six and Iran a year ago in Geneva, under which Tehran halted higher level uranium enrichment in exchange for a limited easing of sanctions, including access to some frozen oil revenues abroad.

Hammond said the expectation was that Iran would continue to refrain from sensitive atomic activity.

He added that Iran and the powers “made some significant progress” in the latest round of talks, which began last Tuesday in the Austrian capital. Hammond said that there was a clear target to reach a “headline agreement” of substance within the next three months and talks would resume next month.

It is unclear where next month's talks will take place, he said, noting that during the extension period, Tehran will be able to continue to access around $700 million per month in sanctions relief.

An Iranian official confirmed the extension, as did Russian Foreign Minister Sergei Lavrov, who echoed Hammond's comments about “substantial progress”.

The deadline for a deal, agreed in July when the two sides missed an earlier target date, was Monday.

The Vienna talks aimed for a deal that could transform the Middle East, open the door to ending economic sanctions on Iran and start to bring a nation of 76 million people in from the cold after decades of hostility with the West.

The cost of failure could be high, and Iran's regional foes Israel and Saudi Arabia are watching nervously. Both fear a weak deal that fails to curtail Tehran's nuclear ambitions, while a collapse of the negotiations would encourage Iran to become a threshold nuclear weapon state, something Israel has said it would never allow.
