Another form of Rwandan justice which has worked alongside Gacaca is the International Criminal Tribunal for Rwanda (ICTR). The United Nations Security Council established the International Criminal Tribunal for Rwanda to "prosecute persons responsible for genocide and other serious violations of international humanitarian law committed in the territory of Rwanda and neighbouring States, between 1 January 1994 and 31 December 1994". The Tribunal is located in Arusha, Tanzania, and has offices in Kigali, Rwanda. Its Appeals Chamber is located in The Hague, Netherlands. Since it opened in 1995, the Tribunal has indicted 93 individuals whom it considered responsible for serious violations of international humanitarian law committed in Rwanda in 1994. The ICTR has played a pioneering role in the establishment of a credible international criminal justice system and is the first ever international tribunal to deliver verdicts in relation to genocide, and the first to interpret the definition of genocide set forth in the 1948 Geneva Conventions. It also is the first international tribunal to define rape in international criminal law and to recognise rape as a means of perpetrating genocide.
