Migrants try to break through a border fence into Macedonia near the Greek village of Idomeni, on February 29 , 2016, where more than 7,000 people are stranded, as anger mounted over travel restrictions on migrants.
Macedonian police fired tear gas as a group of some 300 Iraqi and Syrians forced their way through a Greek police cordon and raced towards a railway track between the two countries. The protest occurred several hours after Macedonia allowed just 300 Syrians and Iraqis to cross before resealing the frontier. With Austria and Balkan states capping the numbers of migrants entering their soil, there has been a swift buildup along the Greece-Macedonia border with Athens warning that the number of people "trapped" could reach up to 70,000 by next month. / AFP / LOUISA GOULIAMAKI (Photo credit should read LOUISA GOULIAMAKI/AFP/Getty Images)
