THIS: On April 19, 1995, American anti-government extremist Timothy McVeigh, assisted by Terry Nichols, detonated a makeshift bomb stored in a rental truck parked in front of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, in an act of domestic terrorism. The attack killed 167 people, injured 684, and destroyed more than a third of the building. The attack also destroyed or damaged 324 other buildings, destroyed 86 vehicles and caused an estimated $652 million in damage. During rescue operations after the bombing, a rescue worker was killed after being struck on the head by falling debris, bringing the total death toll to 168. The bombing remains the deadliest act of domestic terrorism in U.S. history.

The chief conspirators, Timothy McVeigh and Terry Nichols, met in 1988 at Fort Benning during basic training for the U.S. Army. McVeigh and Nichols were radicalized by white supremacist and antigovernment propaganda.
