Judges at the International Criminal Court are weighing whether there is enough evidence to put Bosco Ntaganda, the former leader of a rebel group in Congo's unstable eastern region, on trial.

Prosecutor Fatou Bensouda Monday accused Ntaganda, nicknamed "The Terminator" for his ruthlessness in battle, of 13 charges of war crimes and 5 charges of crimes against humanity for acts including murder, rape, and persecution and recruiting child soldiers. Ntaganda's lawyers say he is innocent.

Ntaganda listened to Bensouda's opening statement gravely. He was indicted in 2006 and was brought to the court in The Hague, Netherlands last year after his group splintered and he fled to neighboring Rwanda. He took refuge in the U.S. embassy before being deported.
