Migrant Crisis: Slovenia sets limit of 2,500 People a Day Slovenia will only allow 2,500 migrants to cross its borders daily - half the number neighbour Croatia has asked for. Interior Ministry Secretary of State Bostjan Sefic said Slovenia could not accept Croatia's request to take 5,000, because Austria's daily limit is 1,500. Most migrants - many from Afghanistan, Syria and Iraq - are crossing Croatia and Slovenia to reach western Europe. The limitation on numbers has led to a build-up of migrants and refugees on Croatia's border with Serbia. Around 40 buses of people were backed up in Serbia on Sunday, and tempers flared between frustrated migrants and overstretched police officers. The migrants have already spent weeks walking from Turkey, via Greece, Macedonia and Serbia. BBC
