The Iranian parliament has voiced opposition to a proposed uranium exchange deal with Russia, the United States and France, state media according to dpa. Parliament Speaker Ali Larijani said that Iran should not be limited in the deal to just exchanging its own uranium with higher enriched uranium, but should also be allowed to purchase it separately. "The stance by the sides involved in the deal indicates imposition and cheating," said Larijani, a former chief nuclear negotiator. The proposal, which originated in Iran, called to increase 3.5- per-cent-enriched uranium from its Natanz plant in central Iran to an enrichment level of 20 per cent at facilities in Russia, with cooperation from the US and France. The 20-per-cent-enriched uranium is supposed to be used for the Tehran reactor, a basic research reactor producing medical isotopes. -- SPA
