The head of Austria's right-wing party is calling German Chancellor Angela Merkel "the most dangerous woman in Europe" for her early liberal migrant policies and is warning of possible civil war if the influx of migrants is not stopped. Heinz-Christian Strache's comments Monday to supporters of his Freedom Party reflected the party's anti-migrant stance and were in stark contrast to more moderate positions being expressed by Norbert Hofer, the party's candidate for Austria's presidency. Slovenia's prime minister says his country has been strengthening border controls — including beefing up metal fences — to prepare for a potential new wave of migration into Europe. Miro Cerar says an increase in numbers of migrants trying to reach the European Union remains a "realistic possibility and we have to be ready for that scenario." Greek police say dozens of residents in an island camp for refugees and other migrants have set fire to part of the facility that handles asylum applications, during a protest over delays in the asylum process.
