The Waco siege, also known as the Waco massacre, was the siege by US federal government and Texas state law enforcement officials of a compound belonging to the religious cult known as the Branch Davidians, between February 28 and April 19, 1993. The Branch Davidians, led by David Koresh, were headquartered at Mount Carmel Center ranch in unincorporated McLennan County, Texas, 13 miles northeast of Waco. Suspecting the group of stockpiling illegal weapons, the Bureau of Alcohol, Tobacco, and Firearms (ATF) obtained a search warrant for the compound and arrest warrants for Koresh and several of the group's members.
