Janjaweed nomads were initially at odds with Darfur's sedentary population due to competition over natural grazing grounds and farmland, a conflict exacerbated by dwindling rainfall and drought.
[17] In Darfur, a western state in Sudan, Libyan leader Muammar Gaddafi supported the creation of the Tajammu al-Arabi (Arab Gathering) militia, which was described by Gérard Prunier as "a militantly racist and pan-Arabist organization which stressed the 'Arab' character of the province".
[19][20] The Janjaweed first appeared in 1988 after Chadian president Hissène Habré, backed by France and the United States, defeated the Libyan army.
[citation needed] Throughout the 1990s, the Janjaweed were Arab partisans who pursued a local agenda of controlling land, and were tolerated by the Sudan Government.
[citation needed] As the insurgency escalated in February 2003, spearheaded by the Sudan Liberation Movement/Army and the Justice and Equality Movement, the Sudanese government responded by using the Janjaweed as its main counter-insurgency force.
[citation needed] On 14 July 2008, the prosecutor of the International Criminal Court filed genocide charges against Sudanese president Omar al-Bashir, accusing him of masterminding attempts to wipe out African tribes in Darfur with a campaign of murder, rape and deportation.
[25] In 2013, the Rapid Support Forces (RSF) were formed from the Janjaweed to fight against rebel groups in Darfur, South Kordofan, and Blue Nile.
Among the dead were three World Food Programme (WFP) workers, triggering the organization to suspend its work in Sudan, where it had been a principal force in alleviating hunger.
[26][27][needs update] Diplomats from the African Union and Saudi Arabia mediated a three-hour humanitarian ceasefire to permit the evacuation of the injured.
