TOPSHOTS Migrants wait for a train heading to Serbia at the Gevgelija railway station, on the Macedonian-Greek border on July 28, 2015. The migrants, among them children and elderly people, are trying to cross Macedonia and Serbia and enter the EU 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.
