TOPSHOT - Migrants and refugees huddled in blankets gather near the northern Greek village of Idomeni as they wait to cross the Greek - Macedonian border on 3 February, 2016. 
A bottleneck of around 7,000 refugees and migrants built up along Greece's border with Macedonia after a protest by Macedonian taxi drivers hampered their crossing, local police said. Most migrants are transported northwards from the Greek-Macedonia border by train or bus, with the taxis demanding to be allowed a share of the business.   / AFP / SAKIS MITROLIDIS        (Photo credit should read SAKIS MITROLIDIS/AFP/Getty Images)
