A Twitter Timeline of the Iran Election

The disputed June 12 Iran presidential election and the ensuing chaos were noteworthy not only for the swiftness with which the government cracked down on protesters but also for the role social media sites helped play in disseminating critical images and news. This was especially true after foreign journalists were essentially barred from reporting. Twitter, in particular, played a key role, allowing opposition supporters to communicate and organize protests, as well as to pass on information about what was happening on the ground to one another and the outside world. Below, we offer a rough timeline of events since the June 12 election, along with a daily sampling of tweets about events in Iran. (Note: Though we've made every effort to select tweets from informed posters, we have not been able to confirm the accuracy of the information contained in the posts. All times are ET, except where noted.)

On election day, long lines and 85 percent voter turnout spurs authorities to extend voting by six hours. Opposition candidate Mir Hossein Mousavi claims victory.

In Tehran, hundreds of thousands of people protest. Government security personnel (Basij) shoot into the crowd; state media later report seven people were killed in clashes. Protests spread outside the capital, with violence between supporters of the reformist Mousavi and police reported. In response to requests from the U.S. State Department, Twitter decides to suspend its scheduled maintenance, which would have interrupted the service for 90 minutes.

Supreme Leader Ayatollah Ali Khamenei speaks publicly for the first time since the election, endorsing the results and saying that Ahmadinejad's 11 million–vote margin of victory is too large to have been the result of fraud or manipulation. Khamenei blames "foreign enemies" and "Zionists" for fomenting the protests and calls for protesters to stop. Amnesty International reports that at least 10 protesters have been killed and four students are still unaccounted for after an attack on Tehran University. Plans are made for a Saturday protest.
