8. Iran
After the massive protests following the controversial elections in 2009 were put down, for a while it seemed that the Tehran government has managed to keep things under control. Then the Arab Spring happened and protests erupted again all over the country. Entire 2011 and part of 2012 were marked by demonstrations unprecedented since the revolution. Violent police response resulted in several protestors killed and many injured, with the unknown number of arrests. There were even reports of police torturing arrested protestors.
