A security crackdown appears to have quelled street protests organised in the wake of Iran’s disputed presidential election.Observers say the hardline Islamist leadership appears to have gained the upper hand, at least for the moment. At least ten protesters were killed in the worst violence on Saturday, along with seven more at the beginning of the week. Many of the dead and injured have been filmed by fellow protesters, with the images viewed around the world on the Internet. Vigils have been held across Europe in memory of Neda Agha-Soltan, a young woman whose death from a bullet wound was captured on video and broadcast on the web. “The people in Iran are not allowed to hold vigils. That is why we urge every Iranian around the world to gather and mourn,” said one Iranian man living in Germany. There have also been calls from inside Iran for memorial services to be held for the dead. In an apparent concession, Supreme leader Ali Khamenei has agreed to a request from Iran’s top legislative body to allow five more days for candidates to lodge complaints over the June 12 poll.
