Iran has rejected as "psychological warfare" assertions by the US intelligence chief that Teheran has enough uranium for two nuclear weapons.
Iranian Foreign Ministry spokesman Ramin Mehmanparast said Monday the remarks by the CIA chief were aimed at creating a "negative perception" of Iran's peaceful nuclear program.
On Sunday, Leon Panetta said Iran probably had enough low-enriched uranium for two nuclear weapons, but that it likely would take two years to build them.
The US and its allies maintain that Iran is trying to develop nuclear weapons, a charge Teheran denies.
The UN Security Council approved a fourth round of sanctions against Iran because of fears over its uranium enrichment program.
