LAUSANNE, Switzerland — The United States, Iran and five other world powers on Thursday announced an understanding outlining limits on Iran’s nuclear program so it cannot lead to atomic weapons, directing negotiators toward achieving a comprehensive agreement within three months.
Reading out a joint statement, European Union foreign policy chief Federica Mogherini said a “decisive step” after more than a decade of negotiations had been achieved. Iranian Foreign Minister Mohammad Javad Zarif followed with the same statement in Farsi. U.S. Secretary of State John Kerry and the top diplomats of Britain, France and Germany also briefly took the stage behind them.
In a tweet, Kerry said there was an agreement “to resolve major issues on nuclear program. Back to work soon on a final deal.”

Mogherini said the seven nations would now start writing the text of a final accord. She cited several agreed-upon restrictions on Iran’s enrichment of material that can be used either for energy production or in nuclear warheads. She said Iran won’t produce weapons-grade plutonium.
Crucially for the Iranians, economic sanctions related to its nuclear programs are to be rolled back after the U.N. nuclear agency confirms compliance.
The officials spoke following weeklong talks that have been twice extended past the March 31 deadline in an effort to formulate both a general statement of what has been accomplished and documents describing what needs to be done to meet a June 30 deadline for a final accord.
The U.S. and five other countries hope to curb Iran’s nuclear technologies that could be used to make weapons. Tehran denies such ambitions but is negotiating because it wants a lifting of economic sanctions imposed over its nuclear program.
Pressured by congressional critics in the U.S. who threaten to impose new sanctions over what they say is a bad emerging deal, the Obama administration is demanding significant public disclosure of agreements and understandings reached at the current round. Iran wants a minimum made public at this point, describing previous two-stage deals as detrimental to their interests, officials say.
The Iranians want any results from talks in the Swiss city of Lausanne described less as a deal and more of an informal understanding.
Found solutions. Ready to start drafting immediately.

Final Ministerial Plenary of these #IranTalks. Now going to meet the press with @JZarif. Good news

The talks resumed Thursday after a flurry of overnight sessions between Kerry and Zarif, and other meetings involving the six powers.
Iran also wants to get rid of sanctions that have stifled its economy. The U.S. and its partners want detailed documents on the steps Iran must take by the end of June on its nuclear program.
One problem, said Zarif, has been differing voices among the other side at the table — the United States, Russia, China, Britain, France and Germany — making it difficult for them “to reach a coordination.”
Big day: #EU, P5+1, and #Iran now have parameters to resolve major issues on nuclear program. Back to work soon on a final deal.

HUGE thanks to our terrific team of U.S. diplomats and experts. Simply could not do #IranTalks without them.

Russian Foreign Minister Sergey Lavrov, who left Lausanne Tuesday, said the two sides were close, the Interfax news agency reported. There are “only a few steps left to take or, in some cases, even-half steps, and some things have already been agreed upon,” he said.
The talks — the latest in more than a decade of diplomatic efforts to curb Iran’s nuclear prowess — hit the weeklong mark on Thursday, shortly before the State Department announced they would go into double overtime from the March 31 deadline for a political framework.
As the sides bore down on efforts to get a deal, German Foreign Minister Frank-Walter Steinmeier canceled a planned visit to Lithuania, Estonia and Latvia. French Foreign Minister Laurent Fabius was also back, less than a day after leaving the city.
By blowing through self-imposed deadlines, President Barack Obama risks further antagonizing lawmakers in both parties who are poised to take their own action to upend a deal if they determine the administration has been too conciliatory.
The initial response to the extensions from Republicans suggested they already reached that conclusion. “It is clear, the negotiations are not going well,” Sens. John McCain of Arizona and Lindsey Graham of South Carolina said in a statement. “At every step, the Iranians appear intent on retaining the capacity to achieve a nuclear weapon.”
