The best foreign media coverage has been from the BBC. Still, most foreign journalists in Iran have been asked to leave and/or face severe restrictions on their freedom of movement. The above links depend largely on reports and video from citizens in Iran, either submitted by email or posted to sites like YouTube, Facebook, Twitter, and Flickr. (Search for the IranElection tag on any of these sites.) Most of these reports are impossible to confirm.
