Right now events in Iran are moving too fast for proper coverage in the MSM. Even the bloggers are slow compared with the flow through Twitter. You can follow it here, here, and here. There is also a YouTube channel up with a constant flow of video from Iran. Though it is unclear how many of these reports can be confirmed, they include the arrest of at least a hundred organizers and journalists, Moussavi’s being put under house arrest, and a lot of violence, including (again unconfirmed) killings across Iran.
