TEHRAN (DPA) - Iran says Russia is losing credibility as a result of delays in the completion of a nuclear power plant at Bushehr in southern Iran.

The comment by Iranian Foreign Ministry spokesman Mohammad Ali Hosseini comes as the director of production of nuclear energy, Ahmad Fayaz-Bakhsh, is holding talks in Moscow to try clarify the situation.

Iran denies claims by Russian contractor Atomstroieksport that Tehran has not made all payments on time.
