The end of communism, the collapse of the Soviet Union and Yugoslavia, and easier global travel have contributed to an increase in human trafficking, with many victims being forced into prostitution, hard labour, agriculture, and domestic service. The conflicts in the former Yugoslavia have also been a key factor in the increase of human trafficking in Europe. The problem is particularly severe in Belgium, the Netherlands, Germany, Italy and Turkey; these countries, along with Thailand, Japan, Israel and the United States are listed by the UNODC as top destinations for victims of human trafficking.
