In this photo taken on Thursday, Sept. 24, 2015, migrant children play at Serbian Orthodox cemetery in no man’s land near the border crossing between Serbia and Croatia near Sid, about 100 km west from Belgrade. Children are resourceful and find joy and distraction for hours in simple objects. Their parents often carry everything they still own in a backpack or two, making dolls and Lego blocks an impossible luxury. (AP Photo/Darko Vojinovic)
