During the coldest weeks of this winter, thousands of refugees shelter in run-down store warehouses in Belgrade.
Especially Hungary and Serbia's other northern neighbors bar their travel.
Without heating, sanitation and only minimal food supply through NGOs on the ground, the refugees keep warm by burning oil-soaked railroad ties.
Instead of heaters, people burn wood they scavenge outside.
The only water source for more than a thousand people.
Hundreds of refugees sleep, huddled close together for warmth, in an old warehouse.
A refugees warms on the hose of a mobile heating unit, which is used to heat the large warehouse.
In an old oil barrel they boil water to wash themselves.
Some refugees leave the camp in buses to be brought in official camps.
