MOSCOW - Russia hopes the next round of six-power talks with Iran on its nuclear program will take place next month, RIA news agency reported on Thursday.

The agency quoted a foreign ministry spokesman as saying the six powers - the United States, Russia, France, Britain, Germany and China - were still negotiating with the Islamic republic on a possible date and location for talks.

Iran is refining uranium to a fissile concentration of 20 percent, which Western experts say is a relatively short technical step from the level that would be required for bombs. Iran says it needs this higher-grade uranium to run its medical research reactor in Tehran.
