Two children of former president Akbar Hashemi Rafsanjani, a political opponent of President Mahmoud Ahmadinejad, have been barred from leaving Iran, the semi-official Fars News Agency said on Thursday. Rafsanjani’s daughter Faezeh addressed supporters of defeated presidential candidate Mirhossein Mousavi on Tuesday when they gathered near the state television building in Tehran in defiance of a ban on opposition protests. Fars did not give a source for its report. It said around 300 people demonstrated outside the Tehran prosecutor’s office on Thursday calling for Faezeh and her brother Mehdi to be arrested.
