The International Criminal Court (ICC) is investigating the recent crackdown on EndSARS protesters in Nigeria.
The Nigerian military is accused of opening fire on peaceful protesters who hit the streets against police brutalities.
According to Nigerian President Muhammadu Buhari some 51 civilians, 11 police officers and seven soldiers were killed during the riots.
Both the police and military have rejected a report by human rights group Amnesty International that the security forces opened fire on protesters, killing and injuring a number of people.
In a statement, the office of the ICC prosecutor said it had received information on alleged crimes.
The examination will “assess whether the legal criteria for opening an investigation under the Rome Statute are met”.
The ICC said it would make findings of the preliminary examination public.
