Iranian Foreign Ministry Spokeswoman Marziyeh Afkham said that Iran and the six major world powers are studying each other's new plans in a bid to narrow down differences, but no agreement has been reached yet, FARS news agency reported.
In reaction to the news reports on a proposal by one of the countries of the Group 5+1 (the five permanent UN Security Council members plus Germany) about the centrifuges connections in Iran's nuclear sites, Afkham said different plans and initiatives were represented and studied by the participating delegations.
"No plan that would be accepted by all the negotiating sides has been agreed upon as yet," she said.
Meantime on Monday, a source close to Iran's negotiating team categorically rejected a news report by the New York Times about a new US proposal for disconnecting Iran's centrifuge cascades instead of reducing their number as "media ballyhoo to ruin the atmosphere of the negotiations".
"There has been a positive and constructive atmosphere in the negotiations in recent days, and although the differences on basic issues are still persistent, the two sides are trying to reduce the differences; but unfortunately some media are trying to disrupt the positive atmosphere of the talks through ballyhoo," the source, who asked to remain unnamed, told FNA.
The 7th round of talks between Iran and the G 5+1 started in New York on Friday.
The two sides held six rounds of negotiations in Vienna to reach a comprehensive deal after they inked an interim agreement in Geneva on November 24.
The Geneva agreement took effect on January 20 and expired six months later on July 20. In July, Tehran and the six countries agreed to extend negotiations until November 24 after they failed to reach an agreement on a number of key issues.
