Curbing the flow of migrants into Europe will be the focus of a meeting held by the leaders of ten countries on Saturday. The Prime Ministers of Albania, Bulgaria, Croatia, Germany, Greece, Hungary, Macedonia, Serbia, and Slovenia are expected to be joined by European Council President Donald Tusk and EU migration commissioner Dimitris Avramopoulos. Romania's Interior Minister Petre Tobă will also be attending. In an interview aired late on Friday by Austrian public broadcaster ORF, Borisov has said he will push for the establishment of reception and accommodation centers for migrants located out of the EU. "To flood states with Greece, Italy and Bulgaria with refugees while Hungary and Austria erect fences at their borders is neither European nor democratic," he has said. The meeting is being called at the initiative of Austria's Chancellor Christian Kern. Enforced external border protection will also be discussed, ahead of the widely expected European Border and Coast Guard that will be launched from Bulgaria on October 06, with Avramopoulos set to attend. Bulgaria fears thousands of migrants might remain locked within its boundaries as Serbia calls for stricter border controls in its western borders as a possible counter-measure against moves by Hungary to send back an increased number of people into its territory. Hungary is looking at Austria as well, with its neighbor working to seal off the common border. Separately, Hungary will hold on October 02 a referendum on whether to accept EU migrant quotas.
