Over 90,000 people have crossed into Chad from Darfur as Sudan became gripped by war when fighting began between Sudan’s army and the paramilitary Rapid Support Forces on April 15th. Amid the chaos, fighting also reignited in the west of the country that is still haunted by 20 years of conflict between Arab militias and non-Arab groups - including the Arab Rizeigat tribe and the non-Arab Masalit - fuelled by competition for dwindling resources. At least 500 people died across Darfur in the first weeks of fighting, according to Sudan’s health ministry, while over 250,000 people in West Darfur were displaced. The figures are likely to have increased since they were reported before a total communication blackout in el-Geneina on 19 May. el-Geneina suffered two waves of violence at the end of April and in mid-May. They both started when Arab militias stormed it, exploiting the army’s non-interference.
