Thousands flee from CAR violence
Thousands of people have fled their homes to escape violence in the north of Central African Republic (CAR).
Aid agencies estimate that more than 7,000 refugees have crossed the border into Chad in the past few weeks.
A BBC reporter who visited the area says refugees claim government troops are systematically killing men and boys they suspect of backing rebel groups.
Central African Republic President Francois Bozize has blamed rebel groups for the unrest.
