"No agreement has been made on any of the topics discussed in the nuclear negotiations," Foerign Ministry spokeswoman Marziyeh Afkham asserted.
She made the remarks in a press conference in reaction to a report published by The Associated Press.
The AP report quoted some diplomats as saying that Iran and the US had mutually agreed on a formula that Washington hopes will reduce Tehran's ability to make what it claimed to be nuclear weapons by committing it to ship to Russia much of the material needed for making such weapons.
"The sort of politically-motivated media campaigns are aimed at damaging the general atmosphere of the negotiations and complicating the settlement of the Iranian nuclear case,” said the FM official.
According to the alleged report, the two parties in the talks are still arguing over how much of an enriched uranium stockpile Iran could have.
But the diplomats have claimed that the newly created catalog enmumerates shipping out much of the material as have been tentatively agreed upon.
Iran and the six global powers wrapped up one week of intensive nuclear negotiations in Vienna on November 24, but they did not reach a long-awaited deal they were supposed to make by the self-imposed November 24 deadline.
