PARIS, Mar. 18 — Russia has informed Iran that it will withhold nuclear fuel for Iran’s nearly completed Bushehr power plant unless Iran suspends its uranium enrichment as demanded by the United Nations Security Council, European, American and Iranian officials said.
The ultimatum was delivered in Moscow last week by Igor Ivanov, Russia’s Security Council Secretary, to Ali Hosseini Tash, Iran’s deputy chief nuclear negotiator, said the officials, who spoke on condition of anonymity because a confidential diplomatic exchange between two governments was involved.
