(UNICEF) – An estimated 535 million children – nearly one in four – live in countries affected by conflict or disaster, often without access to medical care, quality education, proper nutrition and protection, UNICEF said today. Sub-Saharan Africa is home to nearly three-quarters – 393 million – of the global number of children living in countries affected by emergencies, followed by the Middle East and North Africa where 12 per cent of these children reside.
