Why did fighting in northern Central African Republic force people to flee to Chad after 2005?

Starting in June 2005, fighting between government forces and various rebel groups in the northern region of the Central African Republic forced tens of thousands of people to flee across the border into Chad.1

This displacement was driven by several factors:

• Internal Conflict: Ongoing hostilities between the government and rebel factions created an unstable environment, with many cease-fire agreements failing to be fully implemented.1
• Regional Instability: The northern part of the country was subjected to violence that spilled over the border from the conflict in the Darfur region of neighboring Sudan.1
• Rebel Activity: The prevalence of rebel activity in border regions caused populations to move back and forth between the Central African Republic and Chad to escape the violence.2
