"The Americans should make requests which have something to do with realities," Admiral Fadavi told the semi-official Mehr news agency on September 26.
Fadavi added that in Tehran's view "the illegitimate presence" of the United States in the Persian Gulf makes no sense.
Eyre told RFE/RL's Radio Farda on October 5 that despite the "contradictory statements" from Iranian officials, Tehran should still consider the plan and accept it if it finds it in its interests.
In a wide-ranging interview, Eyre, who is a fluent Persian speaker, also said that he didn't know when the U.nited States will announce its decision regarding the terrorist designation of the Iranian opposition group Mujahedin Khalq Organization (MKO).
When asked whether the United States considers MKO a viable opposition group, he said: "No. The U.S. considers the Mujahedin Khalq a terrorist organization. That's it."
Eyre: It takes time. Sanctions are having an impact. We’re hoping that the Islamic Republic will change course and play a more positive role.
RFE/RL: U.S. officials have said that the sanctions are not against the Iranian people. But in practice we’re seeing that small businesses, ordinary people are being hurt by the sanctions.
Eyre: The sanctions are aimed against Iran’s illegitimate and illegal actions. They’re not aimed against the Iranian people. We haven’t been 100 percent successful and, it’s regrettable. We try very hard so that Iranians don’t pay for the actions of their government.
Eyre, who was appointed earlier this year in an effort by the Obama administration to reach out to Iranians directly, told RFE/RL that the United States is concerned about all the Iranian citizens whose rights are being violated in the Islamic republic.
"We work hard so that all Iranians, including Musavi and Karrubi, can enjoy their basic rights including the right to freedom of expression," Eyre said, adding that Washington expresses concern about the human rights situation in Iran in general without mentioning specific individuals.
