The ICC prosecutor announced the opening of a preliminary examination in November 2010 to assess whether alleged crimes committed in the Niger-Delta and the Middle Belt states in the context of armed conflict between extremist group Boko Haram and Nigerian security forces may amount to crimes against humanity and war crimes under the Rome Statute. The preliminary examination also considers whether national proceedings in relation to these crimes are genuine.
According to reports, the OTP is building eight cases to bring to trial. Of these, six cases are against Boko Haram members and two are against members of the Nigerian Security Forces.
