TEHRAN (AFP/Reuters) - A top Iranian nuclear official said Tehran is pressing for the UN nuclear watchdog to ban military strikes against atomic facilities around the world, state television reported on Tuesday. But Irans envoy to the International Atomic Energy Agency, Ali Asghar Soltanieh, denied saying Tehran was ready to hold talks with the West on its atomic drive without preconditions, the TV reported. No comments or interview with TV networks has been made on nuclear talks or conditions, it quoted him as saying. The television had earlier quoted Soltanieh as saying: Negotiations without preconditions is Irans main stance on the nuclear issue. Instead, Soltanieh said he had referred to a letter he sent to the IAEA calling for the UN watchdogs meeting in September to approve an Iranian initiative to prohibit armed attacks on nuclear facilities across the globe. The only issue that was raised was to ban threats and attacks on the worlds nuclear installations, because it is an international issue, he said, the television reported. Irans main policies are not changed and that is to pursue its peaceful nuclear activities within the framework of the IAEA, Soltanieh said. Obama has given Iran until September to take up a six-power offer of talks on trade benefits if it shelves sensitive nuclear enrichment, or face harsher sanctions. Iranian officials have made statements in the past about possible discussions on Tehrans nuclear activities based on mutual respect and without preconditions, while vowing not to back down in the row with the West. But political turmoil in the Islamic state following its June election clouded prospects for dialogue. The West suspects Iran of seeking to build nuclear weapons. Iran, the worlds fifth-largest oil exporter, says its programme is aimed at peaceful power generation and has ruled out suspending or freezing its activities. The poll and its turbulent aftermath have plunged Iran into its biggest internal crisis since the 1979 Islamic revolution, exposing deepening divisions within its ruling elite and also further straining relations with the West. Obamas offer of engagement with Iran if it unclenched its fist ran into trouble after Iran accused the United States and other Western nations of inciting protests after the election, and Washington strongly condemned the governments crackdown. Iranian President Mahmoud Ahmadinejad has signalled a tougher approach towards the West, declaring last month that his next government would bring down the global arrogance, a term used to refer to the US and its allies. Ahmadinejads reformist opponents say the June vote was rigged to secure his re-election. He denies it. The last time Iran held talks with major powers on its nuclear programme was in July 2008 in Geneva. The six powers involved in the issue are: the US, China, Russia, France, Germany and Britain.
