Iran says it will suspend uranium conversion activities from November 22 as part of a European-brokered deal to ease tensions over the country's nuclear program.

In a news briefing Monday, Foreign Ministry spokesman Hamid Reza Asefi described the move as a confidence-building measure. But he insisted Iran would not permanently halt uranium enrichment activities.

Full details of the agreement announced Sunday are not yet available.

European countries had warned Tehran that they would support referring Iran to the United Nations Security Council for possible sanctions if the enrichment program was not stopped.

Uranium enrichment can be used to make material for atomic weapons, but Iran insists its nuclear program is only for peaceful purposes. The United States accuses Iran of developing a secret nuclear weapons program.
