Geneva/N’Djamena – As many as 20,000 people – among them Chadians, Sudanese, and foreign nationals – fleeing the violence in Sudan have arrived so far in neighbouring Chad; a country that shares a 1400km-long border with Sudan. “The majority of those arriving are in dire need of basic humanitarian aid, namely food, water and adequate shelter,” explains Anne Kathrin Schaefer, IOM Chad Chief of Mission.
