Afghans given 'second chance' in Iran

Afghans started their major wave of immigration 3 decades ago after the country became occupied by the Soviet army.
The ensuing years of civil war and the Taleban's reign heightened this and only recently is the immigration route seeing some return journeys.
However, there are still millions of Afghans living in Iran and Pakistan, many of whom have illegal immigration status.
