Iran's top nuclear negotiator said on Tuesday a framework deal with world powers on its nuclear work was "possible this week", although it was not necessary to hold to any such deadline, Reuters reported.
"I believe that if we don't make a breakthrough at this round it's not a disaster," Foreign Minister Mohammad Javad Zarif told France 24 television. "A lot of work has to be done, but there is a great deal of mistrust in Iran."
Zarif will participate in the new round of P5+1 and Iran negotiations which are scheduled to be held in Geneva on November 7-8.
Iran and the five permanent members of the UN Security Council plus Germany known as the P5+1, held a new round of talks on Tehran's nuclear energy programme in Geneva on October 15 and 16.
Both sides announced that the negotiations were held in a positive atmosphere.
Iran submitted a new proposal to the P5+1 during the meetings.
