Hassan* 7, from Iraq, receives warm clothes as he prepares to cross the border from Serbia to Croatia on October 7, 2015. His father, a Shia Muslim, was forced to divorce his Sunni wife by a powerful Baghdad militia and had to flee for his life, leaving his wife and two daughters. He said: "I miss my wife and think about my other two children all the time. I'll go anywhere to live in peace. Anywhere to escape from there."
