At A Glance
The United Nations has described Sudan's western Darfur region as one of the world's worst humanitarian crises.
- 1.9 million living in displacement camps in Darfur
- Many have also fled to Chad and Central African Republic
- Restricted access for peacekeepers and aid workers
The conflict flared in 2003 when rebels in Darfur took up arms, accusing the government of neglecting the region. The government responded with a brutal counter-insurgency campaign.
Since then, civilians have come under attack from government troops, pro-government nomadic militia and rebel groups. The United Nations says as many as 300,000 people may have died. Khartoum puts the figure at 10,000.
The violence has also forced hundreds of thousands of people - mostly farmers and villagers from non-Arab groups - to flee their homes. The majority are living in squalid camps in Darfur and neighbouring Chad.
In March 2009, the International Criminal Court issued an arrest warrant for Sudan's president for war crimes and crimes against humanity in Darfur.
Soon afterwards the government expelled 13 international agencies from Sudan and three local agencies from Darfur.
Since then few reports have been published on the humanitarian situation in the region. News agencies have very limited access, and aid agencies are reluctant to speak out for fear they will be expelled.
A combined United Nations-African Union peacekeeping force began deploying in 2007, taking over from a small, overstretched AU force.
Although violence has fallen from levels seen in 2003 and 2004, fighting escalated again in 2010 and 2011 forcing tens of thousands more people to flee their homes.
The conflict in west Sudan's Darfur region flared in 2003 when two rebel groups rose up against the government, accusing it of neglect.
Khartoum moved swiftly to crush the revolt by the Justice and Equality Movement (JEM) and the Sudan Liberation Army (SLA).
The conflict spilt over into neighbouring Chad and Central African Republic.
The Sudanese government is widely accused of arming militias drawn from Arab tribes who have used scorched-earth tactics against the rebels' communities. Khartoum has denied the accusations.
In March 2009, the International Criminal Court issued an arrest warrant for Sudan's President Omar Hassan al-Bashir for war crimes and crimes against humanity in Darfur, describing the Janjaweed as allies of the Sudanese armed forces. Bashir has dismissed the charges.
Soon afterwards the government expelled 13 international agencies from Sudan and three local agencies from Darfur.
In 2009, the outgoing military commander of U.N. peacekeepers said the conflict was effectively over, and isolated attacks and banditry were the region's main problems.
But fighting escalated in 2010, forcing tens of thousands more to flee their homes.
Exact figures for the number of people killed in the conflict in Darfur are hard to determine. The United Nations says as many as 300,000 may have died since 2003 - a figure disputed by Khartoum, which puts it closer to 10,000.
Many villages have been destroyed and hundreds of thousands of people have fled the violence to squalid camps in Darfur and neighbouring Chad.
International Crisis Group says the removal of so many people from their homes has been part of a government policy of ethnic cleansing, in a bid to cripple support for the rebel movements.
The displaced are mostly African farmers from the Fur, Zaghawa and Massaleit tribes. The Janjaweed come from Arabic-speaking pastoralist communities, which herd camels in northern Darfur and cattle in southern Darfur.
Both the farmers and the pastoralists are Muslim and dark-skinned, and have inter-married for centuries.
The Zaghawa are also camel herders and have strong ties to Chad.
Struggle for resources
Darfur's population of about 7.5 million is scattered over a harsh desert area the size of France.
The region, historically separate and long neglected by Khartoum, lacks basic infrastructure and social services. Experts say the motives for the rebellion were exclusion from political power, lack of roads, schools and water infrastructure.
The Darfur rebels' grievances were similar to those of some 30 armed groups in the south of the country and elsewhere.
Land used to belong to tribes - Darfur means 'the place of the Fur people'. There are at least 36 main tribes in the region.
Some of the Arab people felt left out of a system that gave more "dars" (districts) to non-Arab communities.
Traditionally, conflicts were settled with little or no violence by respected local councils. These were abolished by the Khartoum government after it came to power in a coup in 1989, leaving no mechanisms for resolving disputes peacefully.
The disbanding of the councils coincided with droughts and the encroachment of the expanding Sahara Desert, which forced Arab herders from the north into competition over land with farmers based in villages.
To make matters worse, ethnic differences between the two groups - who used to co-exist peacefully in the main - have been exaggerated by local leaders in the battle over resources.
When Khartoum retaliated against Darfur's rebels, it lit a powder keg.
It is accused of recruiting Arab militias, known as Janjaweed, who are blamed for killings, widespread rape and abductions. Refugees describe them as ferocious gun-wielding men riding camels or horses who burn villages and steal whatever they can carry.
Khartoum has repeatedly denied any links to the Janjaweed, dismissing them as outlaws.
Some of the Janjaweed have now been integrated into the Sudanese military, or have changed sides and joined the rebels. Others still fight in militia groups backing government troops - despite a 2004 U.N. Security Council resolution ordering their disarmament.
Reports suggest Arab tribes in Darfur may also be losing patience with Khartoum. Some Arab communities are said to feel they have been used by the government to fight its battles, scapegoated for atrocities and then excluded from the political process.
The existence of oil in Darfur, revealed in 2005 when Sudan's Advanced Petroleum Company (APCO) began drilling, has led some analysts to wonder how far oil could be guiding Khartoum's actions in the region.
Some experts have suggested the oil reserves could act as an incentive to end the fighting. Drilling is risky during conflict, and if the oil can be extracted, there will be more wealth to go around, they argue.
Many commentators say the conflict in Darfur has been exploited in the struggle for power within Sudan's Islamist movement.
The fighting is not just between government forces and rebel groups, but has also been between and within rebel groups.
Tribal clashes over access to land, conflicts between pastoralists and farming communities, and attacks by criminal gangs add to the region's insecurity, the U.N. Secretary-General's December 2011 report on Sudan said.
Qatar, representing the Arab League, has been working with the African Union, United Nations and Chad in mediating peace talks. But rebel divisions and continued military action means the so-called Doha peace process has so far failed to secure a truce.
Parallel efforts to engage civil society in the process have divided Darfurians into those who are for or against the Doha peace talks, leading to clashes in displacement camps.
The most powerful active rebel groups are JEM and two Sudan Liberation Army factions, one led by Abdel Wahed Mohammed al-Nur (SLA-AW) and one led by Minni Arcua Minnawi (SLA-MM).
SLA-AW has settled in Kampala, Uganda, after being all but expelled from its longtime base in Paris, the Small Arms Survey says. Minnawi moved his base from Khartoum to Juba at the end of 2010, when he took up arms against the government.
In July 2011, the government signed a peace deal – the Doha Document for Peace in Darfur - with the Liberation and Justice Movement (LJM), an umbrella organisation of small rebel groups. ;JEM, SLA-MM and SLA-W refused to join. ;
The rebels are divided over the peace talks, and over whether to fight for changes in Darfur or for a broader national agenda.
Former members of the LJM have joined JEM. And in November, the former deputy chair and lead negotiator for JEM, Mohamed Bahr Ali Hamdeen, formed a breakaway faction willing to negotiate with the government.
Later that month, JEM joined the Sudanese Revolutionary Front, a coalition of rebel groups with the stated aim of overthrowing the national government by all possible means. The coalition is formed of SLA-MM, SLA-AW and the Sudan People's Liberation Movement-North which is active in Sudan's states bordering South Sudan, and East Sudan's Beja Congress.
In December the region's most powerful rebel leader - JEM leader Khalil Ibrahim – was killed and his brother, Jibril Ibrahim, took over.
Sudan's authorities have long hunted Khalil Ibrahim, who had taken refuge in neighbouring Libya under Muammar Gaddafi until the leader's overthrow deprived him of his safe haven. In 2008, his fighters launched a shock attack on Khartoum, killing over 200 people. ; ;
A peace deal signed in 2006 – the Darfur Peace Agreement – was a turning point in Darfur's lengthy conflict. It was signed between the government and SLA-MM, which later abandoned it. It was rejected by both JEM and al-Nur's SLA-AW faction.
Al-Nur argued the deal did not address key demands of the Darfur people, including greater compensation for war victims, more political posts for the SLA, and greater SLA involvement in the protection of returning displaced people and disarmament of pro-government militias. Refugees rioted against the agreement in several camps and students protested in Khartoum.
After the 2006 peace deal, the fighting shifted from a mainly two-way conflict between central government and rebels to a more complex war also involving heavy fighting between various rebel factions.
Originally, the SLA united supporters from the Fur, Zaghawa and Massaleit tribes but, after the 2006 accord, it split increasingly along tribal lines.
Minnawi is a Zaghawa, an ethnic group accounting for about 8 percent of Darfur's population. They took up arms less to oppose the government in Khartoum than to fight the Janjaweed, their rivals in the lucrative camel trade in North Darfur, the Small Arms Survey says. Al-Nur is a Fur, which is the largest ethnic group in Darfur, comprising 30 percent of the population.
JEM is mostly Zaghawa, but it also splintered into many factions.
After the 2006 peace pact, the Sudanese military appeared to support Minnawi's side. His faction was accused of using Janjaweed-like tactics, including raping and killing women from the Fur tribe. Al-Nur's supporters were also accused of gang-raping women for having Zaghawa husbands.
The United Nations and African Union said in 2007 their new focus was to bring the disparate rebel groups together in readiness for fresh peace talks with Khartoum.
Peace negotiations between the government and Darfur rebels were left in ruins after JEM's May 2008 attack on the city of Omdurman where parliament sits, near the capital Khartoum. JEM is the only Darfur rebel group to have attacked the political heartland.
Then in October 2008, President Bashir launched a national initiative for peace with a forum to discuss the conflict, which was attended by AU representatives, as well as Egypt, Libya and Qatar, Sudanese political parties and civic groups. Rebel groups refused to attend, saying they would not negotiate with Khartoum unless the government stopped its violence against civilians.
In February 2009, JEM and Khartoum signed a goodwill agreement paving the way for possible peace talks, and the two sides signed a ceasefire in February 2010 in Qatar, brokered by Chad.
JEM claimed to be both the sole representative of Darfurians and the most powerful rebel group, and threatened to leave the peace process if the government signed a peace deal with any other rebel group. Despite this, the government signed a deal in March 2010 with the Liberation and Justice Movement.
All the armed movements insisted there could be no agreement with Khartoum unless Darfur is reorganized as a single region. It was divided into three states in 1994 - North, South and West Darfur - in what many Darfurians see as an attempt to divide and weaken them.
The rebels were angered when in March 2011 the government announced a plan to create two additional states - Central Darfur and Eastern Darfur – saying it was a bid to divide Darfur further along tribal lines and break up its ethnic powerbases.
Peace talks stalled over another March announcement by Khartoum to hold a referendum on whether to unify Darfur's states into one. JEM said the region was not ready for a poll, because so many people were still living in refugee camps.
The new Central Darfur and Eastern Darfur states were established in January 2012.
Wrangling over peacekeepers
In 2007, a hybrid United Nations-African Union force took over peacekeeping in Darfur from a purely AU force.
The 7,000-strong AU force had been massively overstretched and unable to quell the violence or protect civilians. The U.N. Security Council authorised up to 26,000 troops and police for the new hybrid force.
The deployment of UNAMID (United Nations-African Union Mission in Darfur) followed lengthy wrangling.
China took credit for eventually persuading Sudan to accept the additional peacekeepers. As a major buyer of Sudanese oil and supplier of arms, China is highly influential in Sudan and has come under international pressure to do more to stop the violence.
Peacekeepers face government restrictions on movement and access, including access to camps for the displaced. Some have been threatened with attack by the Sudanese military, according to the U.N. secretary-general's November 2009 report to the Security Council.
UNAMID said it was stepping up patrols in February 2011 and stopped waiting for government clearance to go on trips, after the United States criticised the mission for not doing enough to protect civilians caught up in fighting.
However, the mission continues to face restrictions on flights and patrols. Hundreds of visas are blocked and the authorities often refuse permission to resupply UNAMID team sites, peacekeeping chief Herve Ladsous said.
Insecurity spills across borders
The Darfur conflict spilled over Sudan's western borders into Chad and Central African Republic (CAR), with several armed groups forcing people to flee their homes in all three countries.
Sudan and Chad accused each other of helping rebel movements in one another's countries. Chad was accused of supporting JEM.
Chad said Khartoum supported Janjaweed militias that attacked African farming tribes inside its borders.
Chad's President Idriss Deby is from the Zaghawa tribe whose members live on both sides of the border and are among rebels fighting against Khartoum.
More than 260,000 people have fled to U.N.-run camps in Chad, while a few thousand Chadian refugees have sought shelter in Darfur.
CAR's government accused Sudan of arming a coalition of rebels (the Union of Democratic Forces for Unity) who opposed President Francois Bozize and, in 2006, captured several towns in the northeast. Khartoum denied any involvement.
Deby and Bashir agreed in January 2010 to stop supporting each other's rebels, and the U.N. Panel of Experts said this allegedly resulted in JEM relocating from Chad to Darfur.
It also helped to improve security in Darfur's western region, near the border with Chad, resulting in thousands of people returning home in the area.
In January 2012, Chad President Idriss Deby married the daughter of an alleged Janjaweed militia leader, Musa Hilal. President Bashir was one of the guests, as was the U.N./African Union joint representative for UNAMID, Ibrahim Gambari.
Darfur's humanitarian crisis
In 2011, aid agencies were giving aid to up to 4 million people – about half the population - depending on the season, the United Nations said.
Aid workers face attacks and harassment by militia, rebels, bandits and police. Some have complained that Khartoum has kept them under surveillance and hampered their work with a host of administrative obstacles. Aid workers have been arrested and senior U.N. officials prevented from visiting the region.
U.N. agencies say rebel groups and militias have stolen humanitarian trucks for use in combat.
Conditions are extremely difficult for those who have fled the fighting, some of them two or three times. The camps where they have found shelter are raided by armed groups, and collecting basic materials like firewood is dangerous - men are killed and women raped.
Malnutrition rates are at emergency levels and hygiene in camps is poor.
At the end of 2011, 1.9 million people were living in displacement camps in Darfur and about 80,000 people had been newly displaced during the year, according to U.N. figures. About 288,000 Darfur refugees are in Chad.
A large but unknown number have been sheltering with host families and villages in Darfur, Sudan expert Eric Reeves said.
The security situation has improved in western Darfur, enabling around 60,000 combined returns of IDPs and refugees from Chad to return to areas of origin during the first nine months of 2011, the United Nations said.
Government officials have said they want to close the camps and move the displaced back to their lands.
Until March 2009, some 16,370 aid workers were providing relief to more than 4.7 million people in Darfur, according to U.N. figures.
But Sudan expelled a number of large agencies after the International Criminal Court (ICC) issued an arrest warrant for President Bashir, who is charged with atrocities in Darfur.
The government accused them of passing information to the ICC - allegations they deny.
Thirteen international agencies and three local groups were told to stop working in Darfur and other parts of northern and eastern Sudan.
Those who had their operating licences cancelled included Oxfam, Action Against Hunger, Save the Children, CARE, International Rescue Committee, Medecins Sans Frontieres Holland and the Norwegian Refugee Council.
Since then, there has been little information on the humanitarian situation.
It is impossible for aid agencies to properly assess people's needs, the European Commission says.
The U.N. secretary-general's November 2009 report to the Security Council said the aid agency expulsions contributed to increasing malnutrition levels, particularly in rural areas, where relief assistance is stretched beyond capacity.
The remaining agencies have been forced to increase emergency aid, leaving a significant gap in longer-term development projects including education, environmental protection and livelihoods support, Oxfam said.
The U.N. Panel of Experts on Sudan - which monitors the situation on the ground - has been denied access to some areas. Other independent monitoring mechanisms for the international community have been disbanded or reorganised as joint mechanisms with the Sudanese government.
Human rights abuses
Human rights groups have accused Khartoum - under the aegis of Bashir - of torture and severe repression of political opposition and religious freedoms.
Washington has called the Darfur crisis "genocide", a term Khartoum and many other governments reject.
A U.N.-appointed commission concluded in 2005 that no genocide had taken place, but said there had been heinous war crimes no less serious than genocide. It also said individuals may have acted with genocidal intent.
In 2008, the ICC's chief prosecutor took the momentous step of charging Bashir with masterminding genocide in Darfur, killing 35,000 people and persecuting hundreds of thousands more, and an arrest warrant was issued in March 2009.
Prosecutor Luis Moreno-Ocampo also said 2.5 million people were subjected to a campaign of "rape, hunger and fear" in refugee camps.
The court initially indicted Bashir for war crimes and crimes against humanity, but in July 2010 it issued another arrest warrant for Bashir for genocide.
Bashir is the first head of state charged by an international court since Liberia's Charles Taylor and the former Yugoslavia's Slobodan Milosevic.
The U.N. Security Council has referred dozens of other names of Sudanese war crimes suspects to the ICC.
ICC prosecutors want to try a junior humanitarian affairs minister, Ahmed Haroun, and militia commander Ali Muhammed Ali Abd-al-Rahman, also known as Ali Kushayb.
Haroun was state minister of the interior at the height of the conflict. Moreno-Ocampo said evidence showed Haroun funded the Janjaweed from an unlimited budget and he was seen delivering arms to the militia.
Kushayb was allegedly seen giving orders to the Janjaweed, inspecting naked women before they were raped by men in military uniforms, and participating in summary executions.
The ICC has also charged former JEM and SLA-Unity rebel leaders - Bahar Idriss Abu Garda, Abdallah Banda Abakaer Nourain and Saleh Mohammed Jerbo Jamus - with war crimes.
Frustrated at Khartoum's intransigence over Darfur, Washington tightened sanctions against Sudan. The measures are mostly aimed at companies owned or controlled by the government, including firms in oil and petroleum export-related businesses.
The U.N. Security Council has imposed an arms ban on all non-governmental groups, and sanctions on four Sudanese accused of abuses in Darfur. But these have not been enforced by the Sudanese government, the U.N. Panel of Experts on Sudan said in March 2011.
The U.N. Panel of Experts has a mandate to monitor the sanctions and compliance with U.N. Security Council resolution 1591, passed in 2005.
In 2005, the Council also called on Khartoum to end all aerial attacks in Darfur. The military continues to carry out aerial bombings, although the number of attacks has fallen in recent years.
