French Foreign Minister Laurent Fabius has said Iran nuclear talks will go past their June 30 target date and the negotiators have decided not to set a new date to conclude negotiations.
Fabius told reporters in New York on June 29 that he plans to return to Vienna this week as Iran, Britain, China, France, Germany, Russia, and the United States work to finalize a final deal under which Tehran would curb its nuclear program in exchange for sanctions relief.
Fabius said negotiators “have made some progress, but still it is not the end of the process."
In the Austrian capital, U.S. Secretary of State John Kerry warned it was "too early" to tell if an agreement with Iran is possible.
Iran's state media reported on June 30 that Foreign Minister Javad Zarif departed Tehran for Vienna with nuclear chief Ali Akbar Salehi and Hossein Fereydoon, a brother and close aide of President Hassan Rohani.
Zarif had flown to Tehran on June 28 for consultation with Iran's leadership on ongoing nuclear talks.
The six powers want limits on Tehran's programs that could have a military use. Tehran denies it is pursuing such weapons.
Meanwhile, Russia's foreign minister will meet with Kerry in Vienna on June 30.
Sergei Lavrov told reporters in Moscow on June 29 that he would soon depart for Vienna for the talks.
He did not give any details about the discussions.
