The UN atomic agency said on Friday it will hold in December its first talks with Iran since August over Tehran’s nuclear program, AFP reported.

“The IAEA and Iran have agreed to hold further talks on 13 December in Tehran,” International Atomic Energy Agency (IAEA) spokeswoman Gill Tudor told AFP in an email, without elaborating.

“The aim is to conclude the structured approach to resolving outstanding issues related to Iran’s nuclear program,” she said.

The IAEA wants Tehran to address evidence it says it has suggesting that until 2003, and possibly since, Iran conducted research work “relevant to the development of a nuclear explosive device.”

Parallel diplomatic efforts by six world powers have been aimed at persuading Iran to scale back parts of its current nuclear program because of suspicions that its wants a nuclear bomb.

The last high-level talks between Iran the P5+1 — the U.S., China, Russia, Britain, France and Germany — took place in Moscow in June following earlier rounds in Baghdad in May and Istanbul in April.

Analysts and diplomats told AFP after U.S. President Barack Obama’s re-election this week that a new round of P5+1 talks was possible before the end of the year or in early 2013. Experts also see bilateral US-Iranian talks as possible.

Iran has rejected the IAEA’s information, set out in a major report a year ago, as based on forgeries provided by its enemies. In September Iran’s atomic chief accused the agency of being infiltrated by “terrorists” and saboteurs.

Iran has also accused the nuclear agency of sharing its classified information with Israel.

IAEA chief Yukio Amano told the UN General Assembly this week that Iran is not cooperating with its investigation.

In his annual report to the world body, the head of the International Atomic Energy Agency said talks have intensified over the past year. However, he added, “no concrete results have been achieved” thus far.
