US says Iran nuclear deal deadline may 'slip'
AFP, Thursday 25 Jun 2015

High-stakes talks to nail down a historic deal with Iran to curtail its nuclear programme may "slip" past a June 30 deadline, a top US official admitted Thursday ahead of crunch weekend negotiations in Vienna.

"We may not make June 30, but we will be close," the senior official told reporters as top US diplomat John Kerry prepared to head Friday for what could be the last talks between Iran and global powers on the deal.

The official said the target date to finalise the historic deal -- the main outlines were agreed in April in Lausanne, Switzerland -- would only "slip" by a few days.

"The intent of everybody here -- the P5+1, the European Union, Iran -- is to stay until we get this done, or find out we can't. And our intent is to get it done," the official told reporters, asking not to be named.

Others, including Iranian Foreign Minister Mohammad Javad Zarif, who is due in Vienna on Saturday, have said the deadline may be missed by a few days but until now Washington had insisted it still aimed to get a deal on schedule.

Iran, which has engaged in something of a rapprochement with the West since the election of President Hassan Rouhani in 2013, denies wanting nuclear weapons, saying its nuclear programme is exclusively peaceful.

Under the Lausanne framework, which was also agreed several days late, Iran will downsize its nuclear activities in order to make any attempt to make a nuclear weapon all but impossible.

This includes Iran cutting the number of centrifuges enriching uranium, which is used in nuclear power but also for a bomb when highly purified, as well as slashing its uranium stockpiles and changing the design of a new reactor.

Tighter inspections by the International Atomic Energy Agency (IAEA), the UN nuclear watchdog, would give ample notice of any "breakout" to make a bomb.

In return, UN and Western sanctions that have caused Iran major economic pain would be progressively lifted, although the six powers insist they can be easily "snapped back" in place if Tehran violates the accord.

French Foreign Minister Laurent Fabius will also arrive in Vienna on Saturday, an aide said Thursday, while a source in Brussels said EU foreign policy chief Federica Mogherini was expected "this weekend".

The mooted final accord between Iran and the "P5+1" -- the United States, China, Russia, Britain, France and Germany -- will be a highly complex agreement 40-50 pages long, including several appendices.

It will set out an exact timetable of sanctions relief and reciprocal steps by Iran, as well as a mechanism for handling possible violations by either side.

Tricky issues include how UN sanctions might be re-applied, the reduction of Iran's uranium stockpile and its future research and development on newer, faster types of centrifuges.

Amid unease in Iran's conservative-dominated parliament that Tehran is giving too much away, the country's supreme leader, Ayatollah Ali Khamenei, on Tuesday appeared to throw several spanners in the works.

Western powers have stressed that sanctions will not be lifted until the IAEA has confirmed that Iran has carried out key steps under the accord, something that Kerry said in April would take six months to a year.

But Khamenei, who will have the last word for Iran in the talks, said that banking and economic sanctions imposed by the United Nations and the US must be lifted immediately after the agreement is signed.

"Other sanctions can be removed gradually by a reasonable timetable," Khamenei said at a meeting that included Rouhani and hardline former president Mahmoud Ahmadinejad.

Khamenei also reiterated that Iran would not permit the IAEA, which he described as "neither independent or fair", to visit military sites or conduct "unconventional inspections" at other facilities.

For the P5+1, it is vital for the IAEA to go anywhere it sees fit in order to investigate any suspected attempts to develop nuclear weapons.

"A robust agreement is one which includes an extensive verification element, including if necessary visits to military sites," Fabius said Sunday.

Khamenei also took issue with the length of time that some of the restrictions on Iran's nuclear activities would be in place.

Whether or not Iran can satisfy the world that its nuclear programme is entirely peaceful "will be determined in the last days, by whether or not the outstanding issues that we've been very clear about are in fact addressed," Kerry said Wednesday.

"If they are not addressed there won't be a deal."
