A girl cries as she flees clashes during a protest at the Greek-Macedonian border, near the Greek village of Idomeni, February 29, 2016. Macedonian police fired tear gas to disperse hundreds of migrants and refugees who stormed the border from Greece on Monday, tearing down a gate as frustrations boiled over at restrictions imposed on people moving through the Balkans.
