Rezaei, at a ceremony to mark the liberation of the key port city of Khorramshahr from the Iraqi occupation in 1982, said Iran and the US first should declare their prerequisites for holding any dialogue.

He stressed that otherwise the dialogue would never lead to any establishment of ties.

Rezaei termed the US calls on Iran to destroy its missiles, support the Israeli-favored peace and stop backing Islamic movements as the US pre-conditions for a dialogue with Iran.

Rezaei added that the US itself must stop interfering in Iran's internal affairs, unfreeze Iran's assets and vow not to meddle in Iran's political and security ties with Persian Gulf and Caspian Sea countries.

The remarks by the EC secretary followed an earlier comment by head of the Majlis (Parliament) National Security and Foreign Policy Commission Mohsen Mirdamadi that he had evidence showing Iran had held secret talks with the US despite Foreign Ministry's denials.

Mirdamadi's comment was rejected by the Foreign Ministry and the administration who called on the Ministry of Information to conduct a probe into the affair. The Information Ministry later confirmed Foreign Ministry's denials.

The cabinet further said that the Foreign Ministry is the only authorized body to hold talks with foreign countries and described any talks held outside this channel as 'unofficial'.

The administration furthermore stressed that it will accept no responsibility for any attempt to enter any dialogue with the US outside this channel.
