 There are also many innocent Hutu who remain in the forests of eastern Congo, particularly Rutshuru, Masisi and Bukavu, who have been misinformed by rebel forces that they will be killed upon return to Rwanda.Rebels also use force to prevent these people from returning, as they serve as a human shield.In northwest Rwanda, Hutu militia members killed three Spanish aid workers, three soldiers and seriously wounded one other on January 18, 1997.
