Following a diplomatic frenzy in New York, the Islamic Republic of Iran on Friday went into talks with the UN atomic agency in the Austrian capital of Vienna, their 11th such meeting but the first since President Sheikh Hasan Rouhani's election.

Iran's new envoy to the International Atomic Energy Agency said an agreement would take time.

"This is the first meeting so nobody I guess should expect that in just one day meeting we can solve our problems," foreign minister Reza Najafi told reporters.

Deputy Director General of the IAEA, Herman Nakertis, who heads the IAEA delegation in the negotiations with Iran, said that he welcomes the Iranian readiness for negotiations, expressing cautious optimism about finding ways of resolving issues about the possibility of any military purpose behind Iran's nuclear program.

However, Iran's permanent representative at the IAEA, Reza Najafi, said that "the outstanding issues cannot be solved in one day. We intend to exchange views to resolve these. This is the first meeting, and solving all these problems cannot be expected."

The IAEA regularly inspects Iran's nuclear activities. The main focus of Friday's talks was the IAEA's wish for Iran to address allegations that before 2003, and possibly since, it conducted research work into making an actual nuclear weapon.

Allegations were based in large part on information provided to the IAEA from spy agencies like the CIA and Zionist Mossad, intelligence which Iran rejects and complains it has not even been allowed to see.
