A refugee who fled the conflict in Sudan's western Darfur region adjusts her headscarf at Djabal camp near Gos Beida in eastern Chad June 19, 2008. Friday June 20 marks the U.N. World Refugee Day. Reflecting the violence in Darfur that has swept in both directions across the Chad-Sudan border, there are 250,000 Sudanese refugees scattered in a dozen camps in eastern Chad and 180,000 internally displaced Chadians, U.N. officials say.

The reasons why people flee their homes are becoming increasingly complex and interlinked, the UN has warned as it marks World Refugee Day.

The UN refugee agency (UNHCR) says there are about 11m refugees worldwide and 26m internally displaced people.

It says that nowadays people do not just flee persecution and war.

Other reasons include injustice, exclusion, competition for scarce resources and the human consequences of dysfunctional states, it says.  

Earlier this week, the UNHCR said in a report that the number of refugees worldwide had increased to 11.4 million at the end of 2007.

It said that volatile situation in Afghanistan and Iraq were behind much of the rise.

It was the second year in succession the number had gone up, after five years of falling, the agency said.
