Russia responded to Iran's unveiling of a new uranium production facility, warning the move could hurt progress in negotiations with world powers over Tehran's contested nuclear program, a report said Friday.

An unnamed source in the Russian foreign ministry told Interfax that Iran's announcement does not actually breach its obligations under various international nuclear agreements.

"At the same time, in our opinion, the expansion of Iran's nuclear program activities does not promote the achievement of an atmosphere of mutual understanding between the (P5+1) international negotiating nations and Iran, which is so necessary for the successful continuation of the negotiating process," the foreign ministry source said, according to AFP.

The P5+1 nations are comprised of the five permanent UN Security Council members and Germany.

The group met with Iran for two days of talks in the Kazakh city of Almaty earlier this month that ended devoid of a breakthrough or agreement to meet again.

Days later, Tehran unveiled a new uranium production facility and two extraction mines.

Iranian President Mahmoud Ahmadinejad hailed the advances and boasted of mastery over "the entire chain of nuclear energy."

The world powers suspect Iran of developing a covert program aimed at having the capacity to produce a nuclear bomb. Iran denies the claim and maintains that its work is being conducted for energy and medical purposes
