Gholamhossein Esmaili, the spokesman for Iran's judiciary, was quoted by the semi-official FARS news agency Tuesday as saying that an investigation into the crash had started and several arrests had been made. He did not provide details on how many people had been arrested or what their roles in the incident may have been.Speaking in Tehran on Tuesday, Rouhani called for the punishment of those behind the downing of Ukraine International Airlines flight 752.He said a special court with "a high-ranking judge and dozens of experts" should be established in order to investigate the incident. "This is not an ordinary case and all of world is looking at us," Rouhani said."I announce that we will do the follow up in order to detect all aspects of the event and punishing those responsible," the Iranian leader added. After three days of denials, Iran admitted on Saturday that its military had mistakenly shot down the plane.The admission sparked another wave of anti-government protests in Iran and appeared to expose a rift within the country's leadership. While Tehran has rejected allegations that it tried to cover up the shooting down of the plane, the editor in chief of right-wing Tasnim news agency — which is tied to the Islamic Revolution Guards Corps — criticized Iran's leaders for attempting to lie to the public.Around 30 people have been arrested for taking part in the latest round of protests, according to Esmaili, who described them Tuesday as illegal rallies that had put national security at risk. "The government is accountable and we will fulfill our legal responsibilities but most importantly the people should be assured that such an event should not take place again," Rouhani said, expressing sympathies for the families of the victims. He added that the public deserved to know the details about the cause of the crash. Iran's main insurance agency said the damages that should be paid for the crash could amount to $150 million, Iran's Press TV reported Monday.
