On August 22, 2012, Senegal and the African Union (AU) signed an agreement to establish special chambers embedded in the Senegalese judicial system to prosecute the person or persons most responsible for international crimes committed in Chad between 1982 and 1990. It is expected that only the former dictator of Chad during those years, Hissène Habré, who is accused of thousands of political killings and systematic torture, will be prosecuted.
