The streets are roiling once again in Tehran: Tens of thousands of Iranians turned out on Friday in competing pro and anti-government rallies. Leaders of the Iranian opposition, including Mir Hossein Mousavi, actually came under attack by hardliners. Mousavi had tried to join a march in the city when hardliners attacked him, forcing him to retreat into a car and drive away as his supporters fought off the assailants. The rallies were originally meant to mark “Quds day”—a day in which the government trumpets its opposition to Israel and its support for the Palestinians. The Ayatollah Ali Khamenei had banned anti-government demonstrations on Quds day, but opposition leaders turned out anyway—the first time they have done so since mid-July.
