The EU foreign policy chief, Federica Mogherini, says a final deal between Iran and the P5+1 group of countries over Tehran's nuclear program is "very close" as a July 7 deadline approaches, Press TV reported.
"We are very close," Mogherini told reporters on Sunday as she returned to the Austrian capital, Vienna, the venue of the nuclear talks between Iran and the six world powers over the past nine days.
"The atmosphere is constructive, positive," she added.
The EU official said the negotiating parties are showing the political will to strike a comprehensive deal, adding, "Now it is a matter of seeing all together if this political will manages to translate into political decisions."
Iran and the five permanent members of the UN Security Council - the United States, Britain, France, Russia and China - plus Germany have been holding intense talks at the Palais Coburg in Vienna over the past nine days to hammer out a final deal.
After intense talks between Iranian Foreign Minister Mohammad Javad Zarif and US Secretary of State John Kerry over the weekend, foreign ministers of other members of the P5+1 are returning to Vienna in the hopes of finalizing a deal.
