Iranian women on the frontline of protests

This week, we focus on Iran as the country has been rocked by its largest wave of protests since the Islamic revolution in 1979. Human rights groups outside Iran report that thousands have been killed so far. Yet amid the turmoil, women activists and youth campaigners are at the forefront of the struggle, seeking to chart a new course for the nation after decades of repressive rule under the Islamic Republic. Annette Young talks to Iranian filmmaker, Sepideh Farsi and Tara Kangarlou, an Iranian-American journalist, as they watch their home country, from afar, undergo a seismic transformation.
