HORGOS, SERBIA - SEPTEMBER 16: Migrants throw rocks and other objects at Hungarian riot police as they try to break the border post gate and pull down the razor wire fence on September 16, 2015 in Horgos, Serbia. Hungary has introduced tough new laws to administer the influx of migrants and has declared a state of emergency in two of it's counties close to the border. The new laws have created a dead end for migrants arriving at the Horgos frontier post, resulting in clashes with migrants and Hungarian police. (Photo by Christopher Furlong/Getty Images)
