(UNICEF) – Conflicts and instability in five countries alone have uprooted at least 4.5 million children, UNICEF said on the eve of a United Nations high-level meeting on the global migrant and refugee crisis. “Heartrending pictures have helped galvanize public attention around the fate of children caught in the European refugee crisis, but the issue goes far beyond the borders of Europe,” said Afshan Khan, Director of UNICEF Emergency Programmes. “The world is facing the largest refugee crisis since World War II, with millions of families forced to flee their homes due to conflict and persecution in countries like Afghanistan, Somalia, South Sudan, Sudan or Syria.”
