An Iranian news report quotes a top nuclear official as saying Tehran will "seriously and enthusiastically" study a Russian proposal to enrich uranium from Iran on Russian soil.
The comments by Javad Vaeedi, the deputy head of Iran's National Security Council, were reported Wednesday by the Iranian Student News Agency.
The United States and the European Union have voiced grave concerns that without oversight, Tehran will process uranium to the highly enriched level needed to make an atomic bomb. Tehran says it is seeking a lower grade of enriched uranium to fuel a nuclear power plant.
Wednesday's comments by the Iranian official are the most positive public statements from Tehran since Moscow offered earlier this year to supply enriched uranium for Iran's Bushehr reactor.
The comments are also the first public acknowledgment that Tehran has received the Russian offer.
