Iran nuclear deal 'very close'

Iran and major powers will seek Monday to put the finishing touches to a historic nuclear deal, with both sides saying an accord ending a 13-year standoff lies tantalisingly within reach.

The talks, the latest set of which have dragged on for more than two weeks, aim to nail down an agreement curbing Iran's nuclear activities to make it extremely difficult for Tehran -- which denies any such goal -- to develop the atomic bomb.

There had been optimism that a deal would be clinched over the weekend, but finalising a framework accord struck in April has proved difficult, with talks stumbling on the exact timing of sanctions relief and Iran's desire to have a UN conventional arms embargo lifted.

"We have come a long way. We need to reach a peak and we're very close," President Hassan Rouhani said in Iran Sunday, quoted by the ISNA news agency on a 16th day of talks in Vienna.
"We are so close that if you look down from below you feel as if we have got there, but when you do get there you know there are still some steps to take."

A German diplomatic source warned the talks "could yet fail".

"But we really are nearly there. The decisive moment has arrived. If Tehran is ready to take the final steps then things can go very quickly," the source said late Sunday.

Such an accord, if it can be agreed, approved and upheld by all concerned, would draw a line under 13 years of failed diplomacy and threats of military action.

In return Iran will be granted staggered relief from painful sanctions, although the six powers -- the so-called P5+1 of the United States, Britain, France, Germany, Russia and China -- insist on the option of reimposing the restrictions if Tehran breaches the agreement.

- 'The final phase' -

Foreign ministers from all seven countries -- with the possible exception of China -- were expected to be present in Vienna on Monday.

"I hope we are finally entering the final phase of these marathon negotiations. I believe it," French Foreign Minister Laurent Fabius, who cancelled a trip to Africa to stay at the talks, said Sunday.
The current diplomatic effort dates back to Rouhani's coming to power in 2013.

He sought a rapprochement with the West and an end to his country's diplomatic and economic isolation.

The prospect of a thawing of relations between Iran and the United States unsettles many in the Middle East, however, not least Tehran's rivals Saudi Arabia and other Gulf monarchies.

Israel, widely assumed to have nuclear weapons itself, is also deeply concerned, complaining that the mooted deal will fail to stop its arch foe getting the bomb.

Russian Foreign Minister Sergei Lavrov returned to the Austrian capital on Sunday, joining US Secretary of State John Kerry, Iran's Mohammad Javad Zarif, Fabius, Germany's Frank-Walter Steinmeier and EU foreign policy chief Federica Mogherini.
British Foreign Secretary Philip Hammond, who left Vienna on Sunday afternoon, was expected back on Monday morning. When China's Wang Yi might arrive was unclear.

Several deadlines have been missed over the past more than two weeks of talks, although diplomats insist that the technical aspects of what will be a highly complex agreement are as good as sewn up.

On Monday the terms of a 2013 interim deal freezing parts of Iran's nuclear programme in return for minor sanctions relief expire, although this has been extended several times already.

The deal, if it can be sealed, will however prove a "hard sell" in the US Congress, top Republican and Senate Majority Leader Mitch McConnell said in an interview broadcast Sunday.

"It appears as if the administration's approach to this was to reach whatever agreement the Iranians are willing to enter into," he told Fox News Sunday.
