Iranian Foreign Ministry spokesman Mohammad-Ali Hosseini said on Sunday that Iran would give "deserving" response to any new UN Security Council sanctions over its nuclear program.
"Iran will make necessary decisions based on the nature and content of any resolution," the official IRNA news agency quoted Hosseini as saying at his weekly press briefing.
He made the remarks commenting on new efforts made by the United States to push for a third resolution at the UN Security Council against Iran.
Iranian President Mahmoud Ahmadinejad warned on Saturday that Tehran would take unspecified "decisive reciprocal measures" against any country that could impose additional sanctions on Iran.
Ahmadinejad said in an interview with state television that the latest International Atomic Energy Agency (IAEA) report vindicated Iran over the nuclear issue and the best way for Washington and its allies to "compensate for their mistakes" is to "apologize and pay compensation."
Western countries have accused Iran of using a civilian nuclear program as a cover to develop nuclear weapons, a charge repeatedly denied by Tehran.
The UN Security Council has adopted two resolutions -- one in December 2006 and the other in March 2007 -- in attempts to force Tehran to suspend uranium enrichment activities and give up its nuclear programs.
France, Britain and Germany formally introduced to the UN Security Council Thursday a draft resolution that calls for further sanctions against Iran over its refusal to suspend sensitive nuclear enrichment activities.
The five permanent members of the UN Security Council -- the United States, Russia, China, Britain and France -- and Germany will meet in Washington on Monday on Iran's nuclear issue.
