Reporting from inside Iran has been very difficult for Western reporters over the last several years. The disputed 2009 elections triggered massive anti-government protests. In response, Iran cracked down hard on protesters, and clamped down tightly on journalists' access. That has begun to change with Iran's newly elected president, Hassan Rouhani. Scott Peterson, reporter for the Christian Science Monitor, was recently able to visit and report from Iran for the first time in more than four years. Peterson speaks with host Arun Rath about his trip.
