TOPSHOTS A migrant man carries his child as he walks on train tracks towards the town of Gevgelija, on the Macedonian-Greek border on August 3, 2015. Many of the migrants, among them children and elderly people, are trying to cross Macedonia and Serbia to enter the European Union via Hungary, a country that will finish building its anti-migrant fence on its southern border with Serbia by August 31, ahead of a previous November deadline.
