On October 26, the Islamic State in Iraq and the Levant claimed an attack on the Shah Cheragh shrine in Shiraz, in central Iran. Despite ISIL claiming responsibility, the Islamic Republic already appears to be taking advantage of the attack as a pretext to fiercely suppress protesters. The question, of course, is if the regime’s fiercer suppression will terrorize the Iranian public and help clear the streets or provoke more people to join the ranks of the protesters.
