(Al Jazeera) – “I have friends,” eight-year-old Abdul Karim says from his soft-drink stand inside Iraq’s Ameriat al-Fallujah camp, “but I can’t play with them because I have to work to support my family.” He is just one of more than half a million Iraqi children being forced to leave school and work as their country remains embroiled in crisis, according to UNICEF, the United Nations children’s agency.
