Belarus plainclothes policemen detain a man during an action entitled "Revolution via Social Network" in Minsk, Belarus, Sunday, July 3, 2011. The authoritarian government had tried to thwart the protest by blocking access to Facebook, Twitter and a major Russian social networking site used by the organizers, but police fired tear gas to break up the protest, and several dozen people have been seized by police.
