The Chad-Sudan Conflict (2005–2007) officially started on 23 December 2005, when the government of Chad declared a state of war with Sudan and called for the citizens of Chad to mobilize themselves against the “common enemy”—the United Front for Democratic Change, a coalition of rebel factions dedicated to overthrowing Chadian President Idriss Déby (and who the Chadians believe are backed by the Sudanese government), and Sudanese janjawid, who have been raiding refugee camps and certain tribes in eastern Chad. Déby accuses Sudanese President Omar Hasan Ahmad al-Bashir of trying to “destabilize our country, to drive our people into misery, to create disorder and export the war from Darfur to Chad.”
The problem prompting the declaration of war was an attack on the Chadian town of Adré near the Sudanese border that led to the deaths of either one hundred rebels (as most news sources reported) or three hundred rebels. The Sudanese government was blamed for the attack, which was the second in the region in three days, but Sudanese foreign ministry spokesman Jamal Mohammed Ibrahim denied any Sudanese involvement, “We are not for any escalation with Chad. We technically deny involvement in Chadian internal affairs.” The Battle of Adré led to the declaration of war by Chad and the alleged deployment of the Chadian air force into Sudanese airspace, which the Chadian government denies. The leaders of Sudan and Chad signed an agreement in Saudi Arabia on 3 May 2007 to stop fighting from the Darfur conflict along their countries’ 1,000-kilometre (600 mi) border.
