Article Photos: Iran tightens grip to stem currency fall 3/5

  In this photo taken by an individual not employed by the Associated Press and obtained by the AP outside Iran, an Iranian fire fighter extinguishes a burned motorcycle in a street in central Tehran, near Tehran's old main bazaar, on Wednesday, Oct. 3, 2012. Police threatened merchants who closed their shops in Tehran's main bazaar and launched crackdowns on sidewalk money changers on Wednesday as part of a push to halt the plunge of Iran's currency, which has shed more than a third its value in less than a week.
