In an abandoned warehouse at the back of a bus station in Belgrade, several hundred migrants and refugees, most of them young men from Afghanistan, spend their days trying to keep warm and talking about how they will leave Serbia and continue their journeys towards Western Europe. Officially, since March, there has been no way for migrants and asylum seekers to travel north from Greece other than by successfully applying for family reunification or relocation. But there are options for those who can afford it. Smugglers are charging 1,500 euros to move people from Greece (usually Thessaloniki) to Belgrade, and the same amount again to get them to Western Europe. But many only get as far as the Balkans before running out of money or encountering draconian government policies. Push-backs, detentions, and deportations are common throughout the region, with some activists describing a “ping-pong situation” in which people are endlessly pushed back and forth.
