"EXTRAORDINARY MONITORING"
A final deal would require a vigorous monitoring framework to ensure Iranian compliance. The negotiators have been working out a monitoring mechanism that would involve the IAEA. This has not been considered a sticking point in the nuclear talks.
France, which has demanded more stringent conditions on Iran, said the comments by the Iranian leadership showed that reaching a final deal would be difficult and that in any case there would need to be a mechanism in place to restore sanctions if Tehran violated its commitments.
"Subjects still remain that we aren't agreed on, notably on economic sanctions, and the Supreme Leader has made statements that show there is still a lot of work to be done," Foreign Minister Laurent Fabius told lawmakers.
"We are going to keep the position we have held from the beginning, which is constructive but extremely demanding," Fabius said.
In a ceremony on Thursday to mark Iran's National Day of Nuclear Technology, Rouhani said Tehran's aim was to secure the Iranian nation's nuclear rights.
"Our goal in the talks is to preserve our nation's nuclear rights. We want an outcome that will be in everyone's benefit," Rouhani said in a speech. "The Iranian nation has been and will be the victor in the negotiations."
However, Khamenei said the tentative deal did not guarantee reaching a comprehensive deal by a June 30 deadline.
"What has been achieved so far does not guarantee a deal or even that the negotiations will continue to the end," Khamenei said, adding that an extension of the deadline should not be a problem.
Khameni reiterated Iranian denials that Tehran was seeking to build a nuclear weapon.
A senior Israeli defence official repeated Israel's fears that Iran could still obtain a nuclear weapon if sanctions were lifted immediately and would have more money to spend on arming regional proxies.
"The moment the sanctions are removed, tens of billions (of dollars) will flow to their coffers," Amos Gilad said in a radio interview after Rouhani's speech. "They will get rich. They will have the power to support the entire network of missiles and rockets."
