Amid mounting tensions across Europe over the spike in new arrivals, Germany’s police union called for a scrapping of Europe’s visa-free Schengen travel zone — while Italian police said they had arrested nearly 900 suspected human traffickers since January 2014, but added that the kingpins were at large. In Kos, the migrants, mostly Afghans and Syrians, were being relocated to a local football stadium after camping along roads and beaches for weeks.All Related | More on Greece
