    TEHRAN, Dec. 11 (Xinhua) -- Protesting Iranian students on Monday briefly interrupted a speech by President Mahmoud Ahmadinejad at a university by heckling him and burning his pictures, local Fars News Agency reported.

    Some students, who were members of the banned Students Islamic Association, chanted slogans against the president when he was delivering a speech at the Amir Kabir University, Fars said.

    In response to the students' slogans of "Down with Dictators,"Ahmadinejad said, "it is impossible to establish dictatorship in this country by the name of liberty."

    "We have tasted dictatorship and our revolution has fought against it," the Iranian president said.

    During his speech, some of the female students who were chanting slogans along with the male students, smashed the camera of Iranian state television to the ground, Fars said.

    Some students even set Ahmadinejad's pictures on fire, Fars reported. In responding, the president said, "even if we were burnt for a thousand times, we will never step back even one centimeter."

    The protesting students were confronted by pro-Ahmadinejad students, who began to chant "Ahmadinejad, we support you,"according to Fars.
