The UN nuclear watchdog should continue dealing with the crisis over Iran's nuclear program, Russia's president said Tuesday, urging Tehran to keep its obligations. Russia, a key Iranian ally, has resisted US efforts to bring Teheran before the UN Security Council over its alleged nuclear weapons program, insisting that the disputes be resolved through the International Atomic Energy Agency. Russia is building a nuclear reactor in Iran. "We believe that the IAEA potential in settling all problems related to the Iranian nuclear dossier is far from being exhausted," President Vladimir Putin said after talks with India's Prime Minister Manmohan Singh, according to reports by the Interfax, RIA Novosti and ITAR-Tass news agencies. Putin also voiced hope that Iranians "will observe their obligations, including those they have taken unilaterally."
