On February 28 1993, the United States Bureau of Alcohol, Tobacco, and Firearms (ATF) attempted to execute a search warrant at the Branch Davidian ranch at Mount Carmel, a property located nine miles (14 km) east-northeast of Waco, Texas. An exchange of gunfire resulted in the deaths of four agents and six Davidians. A subsequent 51-day siege by the Federal Bureau of Investigation ended on April 19 when fire destroyed the complex. Seventy-six people, including 21 children and two pregnant women, along with Davidian leader David Koresh, died in the incident. This has come to be known as the Waco Siege or the Waco Massacre.
