TEHRAN, Feb. 18 (Xinhua) -- Iranian President Mahmoud Ahmadinejad on Wednesday repeated his call for "real changes" in the U.S. policies, the official IRNA news agency reported.

    "Bullying powers should make good on their mistakes by making fundamental and real changes to serve the interests of nations instead of killing them," Ahmadinejad told a rally in the central city of Yazd.

    "If you... insist on committing your previous crimes and atrocities, your destiny will be no better than that of former U.S. President Gorge W. Bush," Ahmadinejad said, indirectly addressing current U.S. President Barack Obama.

    In a live interview with state television Tuesday night, Ahmadinejad also called for "real changes" in Washington's policies under Obama.

    "Iran, along with other world countries, is waiting to witness real changes in the U.S. (policies)," Ahmadinejad said in the live interview.

    "Talking about changes is much easier than making them in practice," he said, adding that "the United States needs substantial changes in order to maintain its entity."

    Obama said earlier in February that his administration was "looking for openings" to start face-to-face talks with Iran.

    Obama's predecessor Bush had repeatedly said that diplomatic solution to Iran's nuclear issue was "the first option" although "all options are on the table."

    The United States and its allies accuse Tehran of its intention to develop nuclear weapons under the cover of a civilian nuclear program. Iran has denied the charges and insisted that its nuclear program is for peaceful purposes only.
