“As EU Observer reports, speaking alongside Hungary’s prime minister Viktor Orban on Thursday (7 November), he told reporters the refugees will be allowed into Europe unless the EU provides more support. “Whether we receive support or not, we will continue to aid the guests we are hosting. But, if this doesn’t work out, then we will have to open the doors,” he said.”
