Iranian protesters completed a full week of round-the-clock street demonstrations aimed at bringing down the Islamic republic. Launched under the banner Student Movement Coordination Committee for Democracy in Iran, the protests in recent days have acquired a more varied face: Mothers, sisters, and members of Tehran's revered academic class are joining the campaign to topple the theocratic regime-a campaign until now composed mostly of feisty male undergrads. "It has become almost routine for us to go out at night, chant slogans, get beaten, lose some of our friends, see our sisters beaten, and then return home," wrote one Iranian student. According to the protesters, Iranian riot police are being augmented by "Afghan-Arabs" (al-Qaeda trained fighters), as many regular officers defect to the freedom fighters' side. Riot police used tear gas and iron chains and guns against the demonstrators. They also arrested organizers and charged several with having previous criminal records. Support for the student cause is also growing outside Tehran. Iranians living in the United States used satellite TV channels to beam images of the protests back to residents of Iran. Many said they took to the streets after seeing the bootlegged coverage. Meanwhile, President Bush stepped up a campaign to bring down Iran's nuclear program. The president last week petitioned the International Atomic Energy Agency to begin intrusive inspections of potential nuclear sites in Iran after an IAEA report indicated Iran may be in violation of energy-development norms.
