Sudan accused its neighbor Chad of providing haven and ammunition to the rebels ("basically Chadian forces" ), and the Sudanese government had announced that rebels were moving over the border from Chad to the Darfur region, which is the epicenter of the conflict between Darfuri rebels and pro-government Janjaweed militants; the rebels then moved over some 600 kilometers of desert and scrub from Darfur to the Khartoum metropolitan area.
