Not everywhere. On Friday, the polling day, there were reports that opposition observers were barred from entering some voting stations. Mousavi campaign officials also said that a number of stations in the northwest and south ran out of ballots.
The huge numbers of people voting the government says turnout was more than 80%, one of the highest rates since the Revolution in 1979 meant that some stations were kept open until late Friday night. Many Iranians, especially those in Tehran, have reported that just before voting ended, text-messaging and pro-Mousavi websites were blocked.
