A long-detained opposition leader in Iran on Saturday compared a bloody crackdown on those protesting government-set gasoline prices rising under its supreme leader to soldiers of the shah gunning down demonstrators in an event that led to the Islamic Revolution. The comments published by a foreign website represent some of the harshest yet attributed to Mir Hossein Mousavi, a 77-year-old politician whose own disputed election loss in 2009 led to the widespread Green Movement protests that security forces also put down. Mousavi’s remarks not only compare Supreme Leader Ayatollah Ali Khamenei to Shah Mohammad Reza Pahlavi, the toppled monarch whom Khamenei to this day refers to as a tyrant.
