It was too many Serbian immigrants. Unfortunately. And we all know when and why all that Serb migrations started, no need to remind you. Syrian refugee crisis started much before Russia was involved in that war. And there is many immigrants from Afghanistan, Pakistan, Nigeria, Libya, Ethiopia etc. Europe is not a refugee center and if every single person with problems come to Europe what we native Europeans will do here?
Cause our prime minister is idiot and Angela Merkel's ass kisser. But from the other side, all that immigrants are coming to Serbia from EU (Greece and Bulgaria are EU members if I am correct;) ).
