Around 170,000 people were internally displaced in eastern Chad and living in 38 camps in mid-2010, as a result of internal armed conflict, inter-ethnic violence over land and natural resources, and attacks by bandits against civilians. The majority of internally displaced people (IDPs) had little or no means of sustaining themselves, making humanitarian assistance vital. Chad also hosts 270,000 Sudanese refugees in 12 camps along the eastern border with Sudan, and 81,000 Central African refugees in 11 camps along the southern border with CAR.
