The Zaki-Biam massacre was a mass execution of hundreds of unarmed Tiv civilians by the Nigerian Army between 20 and 24 October 2001. The massacre was a surreptitious operation of the Nigerian army to avenge the killing of 19 soldiers, whose mutilated bodies were found on 12 October 2001, near some Tiv villages in Benue State. The massacre took place in villages including Gbeji, Vaase, Anyiin, Iorja, Ugba, Tse-Adoor, Sankera, Kyado and Zaki-Biam.
