The Branch Davidians, a Christian sect led by David Koresh, lived at Mount Carmel Center ranch in the community of Elk, Texas, nine miles (14 kilometers) east-northeast of Waco. The group was suspected of weapons violations and a search and arrest warrant was obtained by the U.S. federal agency Bureau of Alcohol, Tobacco and Firearms (ATF). The incident began when the ATF attempted to raid the ranch. An intense gun battle erupted, resulting in the deaths of four agents and six Branch Davidians.
