The prosecutor of the International Criminal Court has called for a formal inquiry to begin into war crimes and crimes against humanity in Nigeria.
It follows a decade-long investigation into violence in the north-east involving Boko Haram militants.
Prosecutor Fatou Bensouda said the vast majority of crimes were by “non-state actors”, but that the Nigerian Security Forces also needed investigating.
The conflict has killed over 30,000 and displaced more than two million people.
The ICC’s preliminary examination, which itself began in 2010, has now concluded that the “criteria for opening an investigation into the situation in Nigeria have been met”.
Amnesty International welcomed the “milestone decision” that would bring its “call for justice for victims one step closer”.
What did the prosecutor say?
Ms Bensouda listed a long list of acts allegedly carried out by Boko Haram that constituted crimes against humanity and war crimes.
Specifically they include murder, rape, sexual slavery, torture, persecution, hostage taking and enlisting children under the age of 15 into armed groups.
She said that while “the vast majority of criminality within the situation is attributable to non-state actors”, there was “reasonable basis to believe that members of the Nigerian Security Forces (NSF)” had committed crimes.
They include murder, rape, torture, forcible transfer of population and enlisting children under 15 into armed forces.
Ms Bensouda said that it was her conviction that these crimes should be prosecuted under the Nigerian justice system but, while some efforts had been made, they had not pursued the suspects the ICC believed should stand trial.
She called for financial support for her office from the Nigerian and ICC-funding parties.
Amnesty International’s director of research and advocacy said the prosecutor’s move was “the first meaningful step towards justice that we have seen for victims of atrocious crimes committed by all parties to the conflict in north-east Nigeria”.
