VIENNA — Negotiators at the Iran nuclear talks plan to announce Monday that they’ve reached a historic deal capping nearly a decade of diplomacy that would curb the country’s atomic program in return for sanctions relief, two diplomats told The Associated Press on Sunday.
The envoys said a provisional agreement may be reached even earlier — by late Sunday. But they cautioned that final details of the pact were still being worked out and a formal agreement must still be reviewed by leaders in the capitals of Iran and the six world powers at the talks.
Senior U.S. and Iranian officials suggested, however, there was not enough time to reach a provisional deal by the end of Sunday.
All of the officials, who are at the talks, demanded anonymity because they weren’t authorized to discuss the negotiations publicly.
“We are working hard, but a deal tonight is simply logistically impossible,” the Iranian official said, noting that the agreement will run roughly 100 pages.
The senior U.S. official declined to speculate as to the timing of any agreement or announcement, saying “major issues remain to be resolved.”
Despite the caution, the negotiators appeared to be on the cusp of an agreement.
U.S. Secretary of State John Kerry, who on Thursday had threatened to walk away from the negotiations, said Sunday that “a few tough things” remain in the way but added “we’re getting to some real decisions.”
En route to Mass at Vienna’s Gothic St. Stephens Cathedral, Kerry said twice he was “hopeful” after a “very good meeting” Saturday with Iranian Foreign Minister Mohammad Javad Zarif, who had Muslim services Friday.
French Foreign Minister Laurent Fabius also was cautiously optimistic, telling reporters Sunday: “I hope that we are finally entering the last phase of this negotiation.”
Movement toward a deal has been marked by years of tough negotiations. The pact is meant to impose long-term, verifiable limits on nuclear programs that Tehran could modify to produce weapons. Iran, in return, would get tens of billions of dollars in sanctions relief.
The current round of nuclear talks is now in its 16th day and has been extended three times since the first deadline of March 31 was missed. The mood among negotiators had turned more somber each time a new target date was set.
As the weekend approached, Kerry declared the talks couldn’t go on indefinitely and warned that the U.S. could walk away from the negotiations.
But in another sign that a deal could soon be sealed, Russian news agencies reported that Russian Foreign Minister Sergey Lavrov planned to arrive in Vienna on Sunday evening.
Most other foreign ministers of the six nations negotiating with Iran already are in the Austrian capital and in position to join Kerry and Zarif for an announcement.
Diplomats familiar with the talks said most of the nuts and bolts of implementing the deal have been agreed upon. But over the past week, issues that were previously on the back burner have led to new disputes. Among them is Iran’s demand for a lifting of a U.N. arms embargo and its insistence that any U.N. Security Council resolution approving the nuclear deal be written in a way that stops describing Iran’s nuclear activities as illegal.
A diplomat familiar with the negotiations said disagreements also persist on how long some of the restrictions on imports of nuclear technology and other embargos outlined in any new Security Council resolution will last. The diplomat, who demanded anonymity because the diplomat wasn’t allowed to discuss the confidential talks, said restrictions will last for years, not months.
Meanwhile, Iranians were preparing to celebrate in the event of an agreement. Iran’s semi-official ISNA news agency reported that deputy police chief Brigadier General Saeed Montazer al-Mahdi said the authorities are fully prepared for such celebrations.
Despite Kerry’s relatively upbeat take, comments by Iran’s supreme leader suggested that Tehran’s mistrust of Washington would persist no matter what the outcome of the talks.
Iran’s state-run Press TV cited Ayatollah Ali Khamenei on Saturday as calling the U.S. an “excellent example of arrogance.” It said Khamenei told university students in Tehran to be “prepared to continue the struggle against arrogant powers.”
His comments appeared to be a blow to U.S. hopes that an agreement will lead to improved bilateral relations that could translate into increased cooperation in a common cause— the fight against Islamic State radicals.
Zarif had hinted at just that last week, suggesting a deal acceptable to his country will open the door to joint efforts on that front.
Israeli Prime Minister Benjamin Netanyahu, a fierce opponent of what he considers a deal that is too lenient on Tehran, said Khamenei’s comments showed that Western powers are “caving” in to Iran even as the Islamic republic keeps railing against them.
A nuclear deal will also face serious scrutiny from members of Congress. Senate Foreign Relations Committee Chairman Bob Corker said Sunday he remains skeptical about a possible deal.
“I’m concerned about where we’re going,” the Republican senator said on NBC’s “Meet the Press.”
He said lawmakers will review any agreement carefully to make sure the Iranians are held accountable and that any violations can be enforced.
