Russia's security chief Igor Ivanov met Iranian nuclear officials on Saturday. Ivanov, Secretary of Russia's Security Council, told Iran's official IRNA news agency he had not presented any proposal at a meeting in Tehran with Ali Larijani, Iran's chief nuclear negotiator. "He denied some news agency reports on Russia proposing at a meeting with Ali Larijani a shared enrichment centre in Russia," IRNA's bulletin read. Ivanov gave no indication on whether such a proposal could be handed over at a future meeting.
