Iran says date set for nuclear talks with world powers Iran's principal nuclear negotiator, Saeed Jalili, would announce any agreement on where the talks will take place, Salehi said. The discussions are to be held between Iran and the so-called P5+1 group comprising the five permanent UN Security Council members - the United States, Russia, France, Britain and China - plus Germany. The office of EU foreign policy chief Catherine Ashton, who represents the P5+1, had said as recently as Tuesday that no date nor venue had yet been agreed. Western diplomats accredited to the International Atomic Energy Agency in Vienna also told AFP up to Tuesday that they were not aware of any agreement fixing the place and date of the talks. The talks carry hopes of defusing a tense international showdown over Iran's nuclear activities that has sent oil prices soaring. Israel has brandished the threat of possible military action against Iran's nuclear sites, while the United States has put its energies into sanctions and diplomacy but has not ruled out the military option.
