UN goodwill ambassador Angelina Jolie, on her third trip to Iraq in two years, appealed on Thursday for aid to an estimated 1.6 million civilians who remain uprooted in their homeland. The American actress visited a makeshift camp for displaced Iraqis in a suburb of Baghdad during her one-day trip, the U.N. High Commissioner for Refugees (UNHCR) said in a statement. “This is a moment where things seem to be improving on the ground, but Iraqis need a lot of support and help to rebuild their lives,” Jolie was quoted as telling them. A father of six whose family fled its home four years ago complained his children could not go to school and he could not afford to pay for medical treatment, according to the UNHCR. “It takes a lot of strength for you to survive this life. I don't know if I would be strong enough to survive this,” Jolie told him. She has visited more than 20 hotspots including Iraq, Afghanistan, Pakistan and Sudan since becoming a goodwill ambassador for the U.N. refugee agency in 2001.
