Iran said on Monday it wants a review of the UN-brokered nuclear fuel deal, insisting it prefers to purchase the supplies directly from any world producer. Tehran's latest stance on the high-profile deal came as close ally Moscow and London urged the Islamic republic to accept the offer which aims at applying the brakes on Iran's galloping nuclear programme. 'We are ready to buy the fuel under the supervision of the agency from any producer as we bought this type of fuel from Argentina around 20 years ago with the cooperation of the agency,' said Ali Asghar Soltanieh, Tehran's envoy to the International Atomic Energy Agency (IAEA). Soltanieh, however, did not clarify whether Iran was rejecting the present UN draft, which proposes to ship out Tehran's low-enriched uranium (LEU) abroad for further processing and conversion into fuel. World powers are backing the draft as they fear Tehran could enrich its stock of LEU to very high levels, under the pretext of making fuel for a Tehran reactor, and use it to produce atomic weapons. Tehran denies these charges. Soltanieh told the official IRNA news agency that Tehran was ready for the next meeting regarding fuel supplies for the reactor, an internationally-supervised facility for making medical isotopes. He said Iran also wanted to discuss its 'technical concerns' in a meeting, especially issues regarding 'guarantee for the supply of the fuel as soon as possible' under IAEA supervision. Iran has been hesitating to sign the UN-drafted deal amid stiff opposition from its leaders who suspect the deal backed by Washington will ultimately lead to the suspension of Tehran's uranium enrichment work. On Monday, Iran's Foreign Minister Manouchehr Mottaki, on a visit to Malaysia, called for a review of the deal, a move that could heighten tension with world powers keen to implement the offer. 'We have considered this proposal, we have some technical and economic considerations on that,' Mottaki told reporters in Kuala Lumpur. 'Two days ago we passed our views and observations to the IAEA, so it is very much possible to establish a technical commission to review and reconsider all these issues,' he said, referring to the IAEA. Mottaki added Iran would 'continue enrichment' of uranium for nuclear power stations requiring fuel. Enriching uranium is the most controversial aspect of Iran's nuclear project as the material can be used as fuel for civilian reactors and also to make the core of an atomic bomb. Mottaki insisted Iran still had three options to obtain the fuel -- it could buy it directly from other countries, or enrich the LEU further on its own, or have the fuel processed by another country. Mohammad Ghanadi, a senior Iranian official with the country's atomic body, said that any country 'can give us fuel and if not we will produce it ourselves.' Meanwhile, Britain and Russia demanded on Monday that Iran give a a prompt response to the UN-drafted deal, British Foreign Secretary David Miliband said on a visit to Moscow. 'We both want to see a prompt response from the Iranian regime in respect to the Tehran research reactor proposal,' Miliband said at a joint press conference with his Russian counterpart Sergei Lavrov. Lavrov said Moscow, which is closer to Tehran than any other world power, was counting on Tehran to approve the deal which was thrashed out in Vienna with representatives of Iran, Russia, France and the United States. 'This meeting ended with an agreement ... which we are counting on all the participants, without exceptions, to approve, including Iran,' Lavrov said. The joint stance of London and Moscow comes as top Washington officials have been stepping up pressure on Iran to sign the UN-brokered proposal. US Secretary of State Hillary Clinton on Saturday, urging Tehran to take the offer, said that world powers' paitence has limits. 'Patience does have finally its limits and it is time for Iran to fulfill its obligations and responsibilities to the international community and accepting this deal would be a good beginning,' she said in Jerusalem.
