Protests mark the second anniversary of the "Twitter Revolution" in Iran

According to The Wall Street Journal, approximately 15,000 people gathered in Tehran on Sunday to commemorate the second anniversary of the the disputed presidential election of 2009, which led to the Iranian election protests and the so-called Twitter Revolution.

Sunday’s protests were the the first to be organized by opposition Green Movement since opposition leaders Mir Hossein Mousavi, Mehdi Karroubi and their spouses were placed under house arrest in February. According to sources, the demonstrations were a “silent rally.” Despite the nonviolent tactics of the protesters, the opposition website Kaleme reported that the protests were broken up by police officers and security forces, some wielding clubs as they attempted to disperse crowds and prevent further protests in the capital. Several sources, including The New York Times, reported that the police detained protesters.

According to Asia Times Online, few Iranian websites reported on the protests online. Other sites, however, cite several opposition websites in their reports, including SahamNews and the aforementioned Kaleme.
