Riot police in Macedonia fired tear gas on Friday to disperse thousands of migrants and refugees trying to enter the Balkan country from Greece, according to the Telegraph. Several thousand people from the Middle East, Africa and Asia, many Syrian refugees, spent a cold night in no-man's land after Macedonia on Thursday declared a state of emergency and effectively sealed its southern frontier to migrants and refugees. Riot police behind barbed wire fired tear gas to drive back an angry crowd demanding passage into Macedonia and north to Hungary and the European Union's borderless Schengen zone.
