VIENNA  - The UN atomic agency said Friday it will hold in December its first talks with Iran since August over Tehran's contested nuclear programme, in a first sign of renewed diplomatic activity since the US election."The IAEA and Iran have agreed to hold further talks on 13 December in Tehran," International Atomic Energy Agency 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 programme," 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 programme because of suspicions -- denied by Iran -- that its wants the bomb.Efforts on both "tracks" have however effectively been on hold in recent months because of campaigning for the US presidential elections won on Tuesday by incumbent Barack Obama.The last high-level talks between Iran the P5+1 -- the US, China, Russia, Britain, France and Germany -- took place in Moscow in June following earlier rounds in Baghdad in May and Istanbul in April."The (US) administration was in a very defensive position for the past six months," Mark Hibbs from the Carnegie Endowment for International Peace said this week. "It was also difficult for Iran because they didn't want to negotiate with someone who might not be in office after November."Analysts and diplomats told AFP after 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.Some of the IAEA’s information did come from foreign intelligence services, but not all. In particular the IAEA wants to be given access to the Parchin military base near Tehran, which it visited before but wants to look at again in view of fresh evidence.Iran and the IAEA have held several rounds of fruitless talks this year, the last on August 24. Previous meetings took place in May and June.IAEA chief Yukiya Amano also visited Tehran in May, as did a team led by chief inspector Herman Nackaerts at the start of the year, returning however with no deal.Many in the international community suspect Tehran wants to develop nuclear weapons, and the IAEA says repeatedly that it unable to confirm Iran's assertions that its programme is entirely peaceful.The UN Security Council has imposed four sets of sanctions on the Islamic regime, which coupled with unilateral Western restrictions have begun to cause major problems this year for the oil-rich country's economy.In May the P5+1 set out a package of proposals in talks with Iran calling on it to suspend the enrichment of uranium to 20-percent purities.This is the most worrisome aspect of Iran's programme since this can be relatively easily further purified to the 90 percent needed for the fissile core of a nuclear bomb.The P5+1 also called on Iran to shut its Fordo enrichment facility, which is dug into a mountain and therefore very hard to destroy, and to ship out its stockpiles of 20 percent-enriched uranium.Israel, the Middle East's sole if undeclared nuclear-armed state, has refused to rule out military action to stop its arch-rival also getting nuclear weapons.
