A U.S. anti-terrorism official says Iran is providing money to finance terrorism carried out by the militant group Hezbollah - calling the country quote - "the central banker of terror". In an interview with the Associated Press Monday, Stuart Levey said Iran is a country that has terrorism as part of its budget.Levey - the U.S. Under-Secretary of the Treasury for Terrorism - spoke as Iran faces a Thursday, August 31 U.N. deadline to stop enriching uranium or face possible sanctions. Separately, the United States confirmed it will issue a visa to former Iranian President Mohammad Khatami, who has been invited to speak next month at a multi-faith seminar in Washington. Khatami, considered a moderate among Iranian religious leaders, had advocated dialogue with the U.S. during his term in office, which ended last year.
