Sudanese irregulars have raided as far as 75 kilometers into Chad, and deeper raids are feared because of Chadian rebels serving as guides and advisors. Both Chad and Sudan are hosting each others rebel groups, and are leaving the rebels to fight their war for them. Sudan is the official international bad guy at the moment, and Chad is trying to use that to motivate the UN, or anyone, to help keep Sudanese raiders out. France has several thousand troops in Chad, but they only move if hostile forces approach the capital. No one wants to help out along the border, which is mostly desert.
June 21, 2006: Chadian rebels, based just across the border in Sudan, have been spotted accompanying Sudanese raiders who have been attacking Chadian villages along the border.
June 19, 2006: The SLA (Sudanese Liberation Army), one of the main Sudanese rebel groups in Darfur, have thousands of their armed men camped out in Chad, along the Sudanese border. The SLA men get along with the Chad army units they encounter, and both work together to protect refugee camps, full of Sudanese, from Sudanese raiders crossing the border to attack the camps. It's only a matter of time before the Sudanese army joins the mayhem, because the pro-Sudanese government irregulars have not got the firepower to brush past SLA Chad army units.
