Biafra engaged in genocide against numerous ethnic minority groups within their territory. Largely because said minority groups either didn't want to be a part of an Igbo dominated ethnostate, or were simply not thought of as being as deserving of supplies as Igbo populations.

I'm not saying this to deny that atrocities were committed against the Igbo during the Nigerian Civil War, they were and the victims should be remembered. However, a lot of Western perceptions of the conflict are that of an evil (Muslim) Nigeria versus an innocent (Christian) Biafra, which is reductive and wrong.
