The International Atomic Energy Agency says it has put off a resolution on Iran's nuclear program until Monday, to allow more time for talks on a deal to freeze Tehran's uranium enrichment program.
A spokesman told reporters in Vienna Saturday he expects Iran and diplomats at athe IAEA will come to an agreement.
Hours earlier, Iranian Foreign Minister Kamal Kharrazi said an agreement this month to halt his countrys' nuclear program does not prohibit Iran's use of centrifuges -- key equipment for producing fuel for power plants or nuclear weapons.
Diplomats at the IAEA are trying persuade Tehran to include centrifuges in this month's agreement between Iran, France, Britain and Germany.
IAEA officials are considering referring Iran to the U.N. Security Council for possible sanctions.
The United States says Tehran is secretly developing nuclear weapons -- a charge Iran denies.
