Refugees who've made the perilous journey to Europe are now facing another challenge, the winter cold.
The icy conditions have been especially harsh for refugees living in Serbian and Greek camps. Temperatures have dropped to minus 14 degrees Celsius in some areas, and the shelters weren't designed to handle snow or freezing cold.
Hundreds of refugees have also been stranded in Belgrade as they wait for the borders with the rest of Europe to open. Food has also been scarce, with some people queuing for more than an hour to get basic meals

In Germany, the number of refugees entering the country to seek asylum has dropped significantly.
Two hundred and eighty thousand people arrived in Germany last year. That's about two-thirds less than the previous year. Numbers have declined since the European Union made an agreement with Turkey to limit the arrival of refugees.
