FOREIGN POLICY: Leading Iranian opposition presidential candidate Mir Hossein Mousavi issued a statement warning of “tyranny” Saturday after a tense night in Iran in which state organs proclaimed that incumbent hardline Iranian president Mahmoud Ahmadinejad had won a “landslide” victory by a two-to-one margin, a statistic that defied the belief of many analysts. Voter turnout was an unprecedented 84%. Meantime, reports from western-based Iranians late Saturday said that several people had been arrested in Iran, including the campaign manager for another reformist presidential candidate Mehdi Karoubi, and the brother of former reformist Iranian president Mohammad Khatami, Reza Khatami. Mousavi’s Twitter account said he had been put under house arrest overnight Sunday. Iranian access to Facebook, Iranian cell phones and SMS have been shut down, Iranians said, while international cell phones still worked in Iran. The person coordinating the blackout, Iranians report, is the son of Supreme Leader, Mojtaba Khamenei. MORE
