A mother and her sick infant wait for assistance at a health clinic run by the medical charity Medecins Sans Frontieres (MSF) Holland in Kerfi, a site for displaced Chadians some 50 kilometers (30 miles) south of the eastern town of Gos Beida, June 10, 2008. Reflecting the violence in Darfur that has swept in both directions across the Chad-Sudan border, there are 250,000 Sudanese refugees scattered in a dozen camps in eastern Chad and 180,000 internally displaced Chadians, U.N. officials say.
