Migrants sleep at the train station in Gevgelija
Migrants sleep at the train station in Gevgelija, Macedonia, August 23, 2015. Hundreds of migrants crossed unhindered from Greece into Macedonia on Sunday after overwhelmed security forces appeared to abandon a bid to stem their flow through the Balkans to western Europe following days of chaos and confrontation. Riot remained, but did little to slow the passage of a steady stream of migrants, many of them refugees from the Syrian war and other conflicts in the Middle East, a Reuters reporter at the scene said.
