HORGOS, SERBIA - JULY 16: A child runs past washing left to dry on the border fence close to the E75 Horgas border crossing between Serbia and Hungary on July 16, 2016 in Horgos, Serbia. Serbia has announced that it will start joint army and police patrols on its borders with Bulgaria and Macedonia to curb the illegal entry of migrants and people smuggling. The decision comes days after EU member Hungary began sending back to Serbia all illegal migrants caught within five miles of the border fence that was constructed last year. The new rules have led to hundreds of migrants being stranded along the Serbia-Hungary border. (Photo by Matt Cardy/Getty Images)
