Afghan students attend a class at the Shahid Nasseri refugee camp in Taraz Nahid village near the city of Saveh, some 130 kms southwest of the capital Tehran, on February 8, 2015. Some 5000 Afghan refugees live at the camp which is run by the Iranian Bureau for Aliens and Foreign Immigrants' Affairs (BAFIA), the World Food Program (WFP) and UNHCR. According to the United Nations High Commissioner for Refugees (UNHCR), there are 950,000 registered Afghan residents in Iran -- some of whom have never even set foot in their homeland -- but interior ministry estimates around three million Afghans living in the Islamic republic.
