Iranian Foreign Minister Mohammad Javad Zarif said Saturday there were divisions among the world powers attempting to negotiate a landmark deal with Tehran over its nuclear program.

"We have reached an agreement on some questions, but on others there are still disagreements.... There are differences of opinion within the P5+1 group" of world powers, he was quoted as saying by Iranian news agency ISNA, amid crucial talks in Geneva.

A four-way meeting was held in Geneva today between the foreign ministers of Iran, Germany and UK plus the EU foreign policy Chief Catherine Ashton, and the aim was to reach a settlement of the Iranian nuclear program.

The Iranian ambassador to IAEA said Saturday that Iran expects to sign an accord with the chief of the UN nuclear watchdog on Monday.

"The Islamic republic of Iran has presented a new proposal that includes concrete actions, and we foresee that the text will be finalized on Monday and that the two sides will reach agreement," Reza Najafi told state television.

For his part, Iran's lead negotiator, Deputy Foreign Minister Abbas Araqchi, said after Friday's talks that The meeting was productive but we still have lots of work to do.

Russian Foreign Minister Sergey Lavrov joined the talks in Geneva, where the US, British, French and German foreign ministers rushed on Friday hoping to seal a breakthrough.

French Foreign Minister Laurent Fabius said early Saturday that there were "some points on which we are not satisfied".

"There is an initial draft that we do not accept... I have no certainty that we can finish up" at this stage, Fabius told France Inter radio.

British foreign secretary William Hague said the talks have achieved “very good progress” but important issues remained unresolved and he did not know whether a deal could be clinched by the end of the day.

“We are very conscious of the fact that real momentum has built up in these negotiations and there is now real concentration on these negotiations and so we have to do everything we can to seize the moment,” he told reporters.

The Israeli officials considered that the Americans tricked the Israelis regarding the nuclear deal with Iran.

"We are not bound by the deal," Israeli PM Benjamin Netanyahu said, "the Zionist entity will adopt the suitable options to defend itself."
