Under the terms of the Arusha peace agreements, he was nominated as Higher Education Minister for Culture and Scientific Research.

[4][better source needed] In April 1994, as the violence erupted in Rwanda after President Juvénal Habyarimana's assassination, the French embassy took Ferdinand Nahimana in.
[1] Nahimana was indicted for incitement to genocide and tried at the International Criminal Tribunal for Rwanda's Media Case by Gregory Gordon, together with two others who had been involved with the RTLM: Hassan Ngeze and Jean Bosco Barayagwiza.
The Appeals Chamber also overturned the initial conclusion that there had been an agreement between the RTLM, the CDR, and Kangura to assist in committing genocide.
[4] According to JusticeInfo.net: The appeals judges deemed Nahimana criminally responsible only for not having used his de facto authority over RTLM staff to prevent or stop the broadcast of programmes inciting hatred of Tutsis after the assassination of Hutu president Juvénal Habyarimana on April 6, 1994.
