Serbian police have rounded up a total of 738 migrants in several raids in northern and eastern areas of the Balkan country, part of a nationwide operation launched last week after a shoot-out in which three migrants died. In a statement late on November 2, the police said they had rounded up migrants in the municipalities of Subotica, Sombor, and Kikinda near the Hungarian border in the north and near the town of Pirot in the southeast, near the border with Bulgaria. Last week three migrants died in a shoot-out near Serbia's border with Hungary, a route increasingly used by people smugglers for entering the European Union.
