In April 1995, Timothy McVeigh and Terry Nichols bombed the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma. The terrorist attack destroyed one-third of the building, killed 168 people and injured more than 680. The blast destroyed or damaged 324 other buildings within a 16-block radius, shattered glass in 258 nearby buildings and destroyed or burned 86 cars, causing more than $650 million worth of damage.
Rescue efforts were undertaken by local, state, federal and worldwide agencies. The Federal Emergency Management Agency (FEMA) activated 11 of its Urban Search and Rescue Task Forces, consisting of 665 rescue workers, who assisted in rescue and recovery operations.
