Yemen, Jordan, Syria, Sudan
Three-quarters of a million Iraqis displaced by the war are in Jordan & Syria. They're spread throughout the local communities, where they've had to find places to live, enough to eat, and an education for their children.
The United Nations says more than 4 million Iraqis have been displaced because of the war. Just over 2 million are still inside the country. An equal number is spread across the rest of the Middle East.
Many children in developing countries face hunger, disease and other humanitarian crises. Some are denied their childhoods when they are forced to work or when lengthy wars turn them into refugees or soldiers.
War and poverty take a heavy toll on the world's youngest, and many do not reach the age of five. Lack of access to health care puts babies at risk, and millions of children die from treatable illnesses like diarrhoea, pneumonia and measles that are no longer a serious problem in richer countries.
