The UN has described Darfur as 'the world's worst humanitarian crisis'. On 23 July, the US Congress described it as 'genocide'. Characterising the Darfur war as 'Arabs' versus 'Africans' obscures a complicated reality. Darfur's Arabs are black, indigenous, African and Muslim, just like Darfur's non-Arabs, hailing from the Fur, Masalit, Zaghawa and many smaller tribes.
