A child looks on as a group of migrants from various countries rest on the side of a road after crossing the border illegally from Serbia, near Asotthalom, Hungary July 31, 2015. A month from now Hungary says it will seal its border with Serbia with a 4-metre high, 175-km barrier to keep out migrants streaming through the Balkans, fleeing war, poverty and upheaval in the Middle East and Africa for a better life in western Europe. Migrants are entering Serbia from southern neighbor Macedonia at a rate of over 1,000 per day. REUTERS/Laszlo Balogh
