Armed men have abducted three UN refugee agency staffers, including two Nepali citizens, from Sudan's strife-torn Darfur region, AFP reported quoting a local government official on Monday.

Two Nepalis and a Sudanese national working for UNHCR were abducted Sunday in Geneina, the Capital of West Darfur state, the report added.

"A group of armed men kidnapped yesterday three UNHCR workers, two Nepalese and a Sudanese, from Geneina," Abdelah Mustafa, spokesman for the state government of West Darfur told AFP.

Darfur has been engulfed in a deadly conflict since 2003 when ethnic minority groups took up arms against President Omar al-Bashir's Arab-dominated government, which launched a brutal counter-insurgency.

At least 300,000 people have been killed and 2.5 million displaced in Darfur since then, the UN says.

Bashir is wanted by the International Criminal Court on war crimes and genocide charges related to Darfur, which he denies.

Sudan insists that the conflict in Darfur has ended, and that it wants UN peacekeepers who have been deployed in the region the size of France since 2007 to leave.
