Global numbers of refugees are falling dramatically as people return to former war zones, the United Nations says. Some 9.2m people were refugees in 2005, the lowest figure for 25 years. But in a five-year survey, the UN's refugee agency (UNHCR) warns of "asylum fatigue" in both industrialised and developing nations. UN High Commissioner for Refugees Antonio Guterres warns that public confusion meant people who needed help were seen as a public threat.
