Khakeidja Hamat arrived with her two children a few weeks ago. She said she is "happy to be out of danger, even though we’ve left everything and don’t have much here."
Mrs Hamat and the other displaced people in Koukou are from the Massalit communtiy, one of the main groups targeted by the Janjaweed both in Darfur and Chad.
They account for nearly half the Sudanese refugee population now in Chad.
