The Syrian civil war contributed to pushing the numbers of refugees and those displaced by conflict within their own nation to an 18-year high of 45.2 million worldwide by the end of 2012, the U.N. refugee agency said Wednesday, June 19. Most of the refugees in the world have fled from five war-affected countries: Afghanistan, Somalia, Iraq, Syria and Sudan. <AP Photo/NEWSis/United Nations High Commissioner for Refugees , O.
