Niger’s Penal Code (1961), as amended in 2003, under a chapter entitled “Crimes against humanity and war crimes” in which it provides for the punishment of a list of offences such as genocide, crimes against humanity, and war crimes in the meaning of the 1949 Geneva Conventions and the 1977 Additional Protocols I and II, states:
The courts of Niger have jurisdiction over the crimes set out in this chapter, regardless of the place where these might have been committed. For the crimes committed abroad by a national of Niger against a foreigner, the action of the foreigner or his family or the official notice of the authority of the State where the crime has been committed are not required.
