TEHRAN (Reuters/AFP) - Irans supreme leader accused the United States on Wednesday of war-mongering and of turning the Gulf into an arms depot, hitting back at U.S. accusations that the Islamic state was moving towards a military dictatorship. Lashing out at US Secretary of State Hillary Clinton, Irans supreme leader Ayatollah Ali Khamenei said she had spread lies against the Islamic republic during a tour of the Gulf. In an apparent reference to Hillarys visit to the Middle East earlier this week, Khamenei said that the Americans had dispatched their agent to the region to accuse Irans Islamic system of government. Those who have turned the Persian Gulf into an arms depot in order to milk regional countries for money have now dispatched their official to go around the Persian Gulf and spread lies against Iran, Khamenei said, referring to Hillary at a meeting with visitors from the northwestern city of Tabriz. He said recent moves by Washington officials were suicidal for the US state television reported. But no one believes these lies because they know that America is the real war-mongering state. They have turned the Persian Gulf into an arms depot, he said. They invaded Afghanistan and Iraq and are now accusing the Islamic Republic. Everybody knows that the Islamic Republic is for peace and brotherhood among all Islamic states in the world, Khamenei said, state television reported. Khamenei, Irans top authority, said the Iranian people had punched its enemies in the mouth by turning out in large numbers to rallies last week marking the 31st anniversary of the 1979 Islamic revolution. Khamenei, who like other Iranian leaders accused the West of stoking post-election unrest and meddling in Irans internal affairs, accused arrogant powers of opposing the Islamic Republic because of its call for justice in the world. We should mourn the day when the global imperialism praises us, he said. Irans Foreign Ministry spokesman Ramin Mehman-parast told ISNA news agency that the Islamic republic will not suspend its sensitive high level enrichment in return for radioisotopes as offered in a letter by three world powers to the UN atomic watchdog. In Geneva, a UN report said that Iran has rejected calls to release all political prisoners and accept an international inquiry into violence after last Junes contested presidential elections.
