The three UN Officials emphasized the importance of justice and accountability in responding to human rights abuses and grave violations that constitute atrocity crimes, but also as a critical aspect of prevention of these crimes.
"While his victims' pain cannot be erased, they can take some comfort in seeing justice prevail".
During the sentencing, Mr Fremr remarked that Ntaganda was not only guilty of persecution as a crime against humanity, but that he had also personally murdered a Catholic priest, setting an example for his soldiers to follow. He's the first person to be found guilty of sexual slavery.
Prosecutors focused on two specific attacks involving Ntaganda's militia, one in late 2002 and another in early 2003.
Ntaganda was a "key leader" who gave orders to "target and kill civilians", Judge Fremr said in the ruling.
"Men, women and children and babies were found in the field", said Fremr, according to the BBC. "Some bodies were found naked, some had hands tied up, some had their heads crushed". Ntaganda himself used child soldiers as bodyguards. Lawyers representing victims in the case had called for a life term. "I hope that today they will have a small measure of relief knowing that Ntaganda will be behind bars for a very long time", Van Wouderberg said.
Most of the charges against Rwandan-born Ntaganda, 46, related to a series of gruesome massacres of villagers carried out by his fighters.
After years of being on the radar and being wanted Bosco Ntaganda surrenders to U.S. embassy in Kigali. Experts say he may have turned himself in because fighting within M23 caused him to fear for his life.
Ntaganda, dressed in a blue suit and shirt and wearing a red tie, showed no emotion as the sentence was passed in the high-security courtroom.
His charges include of murder, rape, and conscripting child soldiers - some of whom were also raped and used as sex slaves.
On 7 November 2019, Trial Chamber VI of the International Criminal Court ("ICC") (https://www.ICC-CPI.int/), unanimously, sentenced (http://bit.ly/32mJ6j9) Bosco Ntaganda to a total of 30 years of imprisonment.
The ICC is an global court set up in 2002 to prosecute war crimes and crimes against humanity when member states are unable or unwilling to do so.
Prosecutions have not always been straightforward, however.
But ICC rules cap sentences at 30 years. The convictions of the former Congolese vice-president Jean-Pierre Bemba for war crimes and crimes against humanity were overturned a year ago. The ICC's focus so far on Africa has angered some on the continent who see the global body as unfairly targeting Africans.
