Iran's troubled currency fell to a new low against the U.S. dollar on December 10 amid continued unrest and the country's increasing isolation in the face of Western criticism of its security crackdown and ties to Russia. The dollar was selling for as much as 370,200 rials on the unofficial market on December 10, up from 367,300 the day prior, according to the foreign exchange site Bonbast.com. The rial has lost 13.8 percent of its value since nationwide protests erupted after the death in police custody of a 22-year-old Kurdish Iranian woman, Mahsa Amini, on September 16.
