The Ahmići massacre was the murder of approximately 120 Bosniak civilians by members of the Croatian Defence Council in April 1993, during the Croat–Bosniak War. The massacre was the culmination of the Lašva Valley ethnic cleansing committed by the political and military leadership of the Croatian Community of Herzeg-Bosnia. It was the largest massacre committed during the conflict between Bosnian Croats and the Bosniak-dominated Bosnian government.
