(Newsweek) – Almost two years after the trial opened, Congolese military commander Bosco Ntaganda will take the stand on Wednesday at the International Criminal Court (ICC), charged with 13 war crimes and five crimes against humanity. Ntaganda’s charges —including the murder and rape of civilians and “the recruitment, use, rape and sexual slavery of children”—date back to 2002 and 2003, while he was deputy chief of the general staff for Force Patriotiques pour la Libération du Congo (FPLC), a rebel group in eastern Congo.
