The violence in Darfur is increasingly spilling over to neighboring Chad. Attacks in Chad have killed around 200 people over the past week. It is estimated that 12,000 Chadians have been displaced since November 4th. Survivors describe their attackers as Arab nomad tribes, both Chadian and Sudanese. Many victims were burned alive in their homes.
