The Asaba massacre occurred on 7 October 1967, during the BiafranCivil War in Nigeria. Federal troops of Nigeria entered Asaba, rounded up as many as 500 Igbo men of Asaba and shot them.
The victims were buried in mass graves. This is against Asaba tradition, especially since the men being buried included titled chiefs.
In 2001 a commission to investigate human rights violations in Nigeria was carried out. During the commission, Yakubu Gowon, who was the head of state of Nigeria from 1966–1975, apologized for the atrocities committed during the war, including the Asaba Massacre.
