Over the course of four years of war in Syria, over 4 million refugees have fled the country. Naturally, many of those 4 million are children.

Of course, many of Syria’s children aren’t at all that lucky. Head to The Atlantic to visit the rubble, hospitals, battlefields, and refugee camps where Syria’s youngest are bearing the brunt of this war.
