Sudan: Factbox - Key facts about the conflict in Darfur

June 15 (Reuters) - Sudan has won a diplomatic victory by accepting a joint U.N.-African Union peacekeeping force in Darfur on terms that buy it more time and stave off sanctions, analysts say. After months of negotiations, Sudan accepted the joint force of troops and police on Tuesday.

Here are some facts about the conflict in the Darfur region.

* THE CONFLICT:

-- Rebels in Sudan's western Darfur region took up arms against the government in February 2003, saying Khartoum discriminated against non-Arab farmers there.

-- Khartoum mobilized proxy Arab militia to help quell the revolt. Some militiamen, known locally as Janjaweed, pillaged and burned villages and killed civilians. The government has called the Janjaweed outlaws and denied supporting them.

-- Experts have estimated that at least 200,000 people have been killed and more than 2 million driven from their homes in the region since early 2003, some crossing the border into Chad, exacerbating a refugee crisis there. Sudan says 9,000 have died.

-- The United Nations calls Darfur one of the world's worst humanitarian crises. The United States says the violence in Darfur amounts to genocide.

* CEASEFIRES:

-- A ceasefire was agreed in Darfur in April 2004. The African Union sent 7,000 peacekeepers with a mandate to monitor the peace and protect those displaced in the camps. The ceasefire has been violated frequently, with fighting blamed on government troops, rebels and Janjaweed militias.

-- A peace deal in May 2006 was signed by only one of three rebel negotiating factions. It was almost immediately rejected by many in Darfur who said it did not go far enough to ensure their security. A new rebel coalition has since formed and renewed hostilities with the government.

* PEACEKEEPING FORCE FOR DARFUR:

-- In August 2006, the U.N Security Council adopted a resolution for deployment of a "hybrid" U.N.-AU force of 22,500 in Darfur to replace and absorb the present African Union force, which has been unable to stem the violence.

-- Sudan had already agreed to allow an operation involving technical U.N. support personnel to deploy to Darfur. The "heavy support package" included some 3,500 U.N. military and police personnel.

-- The AU said on Tuesday that Sudan had now agreed to allow an operation involving a force of up to 23,000 troops and police after "clarifications" from AU and UN officials. The majority of the troops would be African.
