A homegrown terrorist, Timothy McVeigh detonated a truck bomb in front of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995. The attack, commonly referred to as the Oklahoma City bombing, claimed the lives of 168 people, including 19 children. A Gulf War veteran, McVeigh was seeking revenge against the federal government for the 1993 siege of a compound belonging to the religious group Branch Davidians in Waco, Texas. The siege ended in the deaths of sect leader David Koresh and 75 of his followers. The bombing of the Murrah building took place on the two-year anniversary of the Davidians' deaths. McVeigh was convicted of 11 federal offenses and was executed on June 11, 2001.
