Iran rial protests riot police october 3 2012

Iranian riot police stand next to a garbage container which is set on fire by protesters in central Tehran, near the main bazaar, on October 3, 2012, in the first sign of public unrest over Iran's plunging currency. The rial, lost more than half of its value since last week as the plunge has greatly increased inflation in Iran, which is widely seen as far higher than the official 23.5 percent given by the central bank.
