Former Congolese warlord Bosco Ntaganda, nicknamed “The Terminator,” goes on trial before the International Criminal Court Wednesday, accused of war crimes including the rape of child soldiers by his own rebel army. The once feared rebel commander faces 13 counts of war crimes and five of crimes against humanity. He has pleaded not guilty. Presiding Judge Robert Fremr will open proceedings against Rwandan-born Ntaganda at 0730GMT at the court’s Hague-based headquarters. ICC’s chief prosecutor Fatou Bensouda will speak first, followed by Ntaganda’s lawyers and those representing some 2,149 victims in the case. Prosecutors say Ntaganda played a central role in ethnic attacks on civilians in the mineral rich but restive northeastern Congolese province of Ituri in 2002-3, in a conflict that left some 60,000 dead since 1999. At a hearing a year ago to confirm charges against Ntaganda, chief prosecutor Bensouda accused the former warlord of allowing his fighters to rape child and women soldiers in his own rebel army, or keep them as sex slaves. Ntaganda, 41, was once one of the most wanted fugitives in Africa’s Great Lakes region until he unexpectedly walked into the US embassy in the Rwandan-born capital Kigali in March 2013 and asked to be sent to The Hague. He was the founder of the M23 rebel group that was defeated by the Congolese government in late 2013 after an 18-month-old insurgency in the vast Democratic Republic of Congo’s North Kivu region.
