And we want the change in behaviour that should follow from that change.

“We will provide new aircraft for Iran”, Akhoundi said.

Rouhani touted the deal as Iranian security hawks began attacking it, a day after Supreme Leader Ayatollah Ali Khamenei described some of the world powers that signed it as “untrustworthy”. “It had nothing to do with the nuclear talks“, he said.

Tehran and Washington had informal discussions in 2001 when United States troops invaded Afghanistan to oust the Taliban from power after the September 11 attacks.

The United States, in contrast, he said, had backed Israeli “atrocities” in Gaza a year ago.

“We have no negotiations with America about various global and regional issues”. Khamenei asked.

During the sanctions regime, Iran tried to circumvent the measures by buying second-hand civilian aircraft from third companies and managed to keep its national carrier and other airlines going by renting aircraft from others.

In London, Cameron’s spokesman said Cameron told Rouhani that the nuclear deal marked a fresh start in relations and that he was committed to re-opening the British embassy in Tehran. We had a fatwa, declaring nuclear weapons to be religiously forbidden under Islamic law.

“If they are afraid of us having entry because we might find something years later, I can assure you our intelligence community is completely comfortable that 24 days is not enough time for them to be able to evade our technical means, our capacity to observe”, Mr Kerry said. Iran also supports insurgents in Yemen and the State Department says it is a primary sponsor of terrorism in the Middle East.

The White House said on Friday that Jubeir had welcomed the accord.

The deal, he said, closes off Iran’s pathway to nuclear weapons; allows for “unprecedented” 24/7 monitoring of key nuclear facilities; and gives worldwide inspectors access to the country’s nuclear supply chain.

Iran calls its Lebanese ally Hezbollah a “resistance movement” while the USA describes it a terrorist group. The West suspects the programme was aimed at making a nuclear bomb, something Iran denies.

But he praised President Hassan Rouhani and Iran’s negotiators. “If we don’t choose wisely, I believe future generations will judge us harshly for letting this moment slip away”, he said while trying to sell the deal which was expected to become his legacy.

“The text that has been prepared, whether it is approved or not, they have done their part and they should have their reward”, he added.

“By solving the artificial crisis about its nuclear program diplomatically, a new opportunity for regional and worldwide cooperation has emerged”, Zarif said.
