Greek authorities will investigate whether a parents' association's strong objections to planned lessons for refugee children at a northern primary school constitute a breach of anti-racism laws. The government wants to integrate refugee and migrant children into the state education system. The European Union has given final approval for the launch of a new border and coast guard, paving the way for it to start work next month. Slovak Interior Minister Robert Kalinak said Wednesday that the new agency will help Europe confront the challenges to its passport-free travel zone known as the Schengen area. A pool of 1,500 border guards and technical equipment will be on standby to rapidly deploy to countries struggling with extraordinary migration flows. A Serbian government minister says the Balkan country should consider applying "more drastic" measures, including border barriers, to reduce the number of migrants entering the country. Hungary's anti-migration prime minister says the future of the European Union will be decided at Bulgaria's border with Turkey, not in Brussels, and is urging the EU to provide more money to Bulgaria to help boost its border defense. Prime Minister Viktor Orban and Bulgarian counterpart Boiko Borisov inspected a fence topped with razor wire in the Bulgarian border village of Lesovo on Wednesday, part of a route used by migrants trying to enter the EU. Borisov, who is seeking immediate assistance of 160 million euros ($180 million) from the EU to bolster Bulgaria's border security, said that "without joint efforts by all EU states, a lasting solution cannot be found." European Commission President Jean-Claude Juncker says solidarity cannot be imposed on EU member countries amid vehement opposition in some states to his refugee quota scheme.
