A migrant takes a picture with a mobile phone as he and others walk towards the Hungarian border after arriving at the train station in Botovo, Croatia September 24, 2015. Almost 50,000 migrants have flowed into European Union-member Croatia via Serbia in little over a week since Hungary, northern neighbour to both countries, barred their entry to the EU by sealing its border with Serbia with a metal fence. Croatia is sending the migrants north across its border with Hungary, which passes them on to Austria, but Zagreb says it cannot cope with the pace, leading to desperate and sometime angry scenes at over-crowded camps and railway stations.
