The Oklahoma City bombing was a domestic terrorist bomb attack on the Alfred P. Murrah Federal Building in downtown Oklahoma City on April 19, 1995. Carried out by Timothy McVeigh and Terry Nichols, the bombing killed 168 people and injured more than 680 others.

The blast destroyed or damaged 324 buildings within a 16-block radius, destroyed or burned 86 cars, and shattered glass in 258 nearby buildings, causing at least an estimated $652 million worth of damage.

Within 90 minutes of the explosion, McVeigh was stopped by Oklahoma State Trooper Charlie Hanger for driving without a license plate and arrested for illegal weapons possession.

Forensic evidence quickly linked McVeigh and Nichols to the attack; Nichols was arrested, and within days both were charged. Michael and Lori Fortier were later identified as accomplices. McVeigh, an American militia movement sympathizer who was a Gulf War veteran, had detonated a Ryder rental truck full of explosives parked in front of the building.

McVeigh's co-conspirator, Nichols, had assisted in the bomb preparation. Motivated by his hatred of the federal government and angered by its handling of the 1993 Waco siege and the Ruby Ridge incident in 1992, McVeigh timed his attack to coincide with the second anniversary of the deadly fire that ended the siege at Waco
