Bosco Ntaganda was found guilty of 13 counts of war crimes and five counts of crimes against humanity in July. The long list of offenses, committed in the Democratic Republic of the Congo in 2002 and 2003, included murder, rape, sexual slavery, enlisting child soldiers, persecution, forcible transfer and deportation, pillage and intentionally directing attacks against civilians.
The sentence is the longest handed down by the ICC and he also becomes the first person to be convicted of sexual slavery.
In a statement, the ICC said the sentencing was unanimous. The time Ntaganda had already spent in detention, from March 22, 2013, to November 7, 2019, would be deducted from his sentence, the Hague-based court said.
The defense and prosecution has 30 days to appeal.
The ICC issued an arrest warrant for Ntaganda — who fought for various rebel groups before becoming a general in the Congolese army — in 2006.
