    TEHRAN, Nov. 3 (Xinhua) -- Iran's Supreme Leader Ayatollah Seyyed Ali Khamenei said Tuesday that there has been no change in the U.S. approach toward Iran, the satellite Press TV reported.

    "The U.S. approach toward Iran has been in contradiction with the slogan of bringing change to its policy," Khamenei was quoted as saying.

    "On the one hand, Americans talk of negotiations, and on the other hand, they continue to threaten," Khamenei told a group of students on Tuesday.

    Referring to the nuclear talks between Iran and the world major powers, he said the Iranian nation will not bow to any conditions which would undermine its rights.

    "If anyone intends to violate the rights of the Iranian nation, the nation will firmly stand up to them and will make them kneel down," he added.

    Khamenei said as long as the United States wanted "to turn backt he time and seek dominance over Iran," it could by no means compel the Iranian nation to retreat, the report said.

    He made the remarks on the eve of the 30th anniversary of the seizure of the U.S. embassy in 1979.

    Iranian government has organized an anti-U.S. rally on Wednesday before the ex-U.S. embassy in Tehran to mark the anniversary of the embassy seizure.

    The United States broke off diplomatic ties with Iran in 1980 after a group of Iranian students seized the U.S. embassy in Tehran and captured some 60 U.S. diplomats in 1979, with 52 of them being in captivity for 444 days in the hostage crisis.
