A rapprochement agreement between Chad and Sudan, signed January 15, 2010, marked the end of a five-year proxy war. The normalization of relations led to the repatriation of Chadian rebels from Sudan, the opening of the border between the two countries in April after seven years of closure, and the deployment of a joint force to secure the border, though attacks on civilians in the area continue. President Idriss Déby visited Khartoum, Sudan's capital, in February for the first time in six years; and in July Chad, a state party to the International Criminal Court, hosted Sudanese President Omar al-Bashir, earning the dubious distinction of being the first ICC member state to harbor a suspect from the court. The Chadian government clashed with rebel forces in eastern Chad in January and April. Criminality, banditry, kidnappings, carjackings, and armed robbery targeting humanitarian agencies led to the withdrawal and temporary suspension of some humanitarian operations.
