Question: What kind of attack does Alfred P. Murrah Federal Building and Oklahoma City National Memorial have in common?
Context: The Alfred P. Murrah Federal Building was a United States federal government complex located at 200 N.W. 5th Street in Downtown Oklahoma City, Oklahoma, United States.  It was the target of the Oklahoma City bombing on April 19, 1995 at 9:02am, which killed 168 people, 19 of whom were children under the age of six.  Half of the building collapsed seconds after the truck bomb detonated.  The remains were imploded a month after the attack, and the Oklahoma City National Memorial was built on the site. Terry Lynn Nichols (born April 1, 1955) is an American who was convicted of being an accomplice in the Oklahoma City bombing.  Prior to his incarceration, he held a variety of short-term jobs, working as a farmer, grain elevator manager, real estate salesman and ranch hand.  He met his future conspirator, Timothy McVeigh, during a brief stint in the U.S. Army, which ended in 1989 when he requested a hardship discharge after less than one year of service.  In 1994 and 1995, he conspired with McVeigh in the planning and preparation of the Oklahoma City bombing – the truck bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, on April 19, 1995.  The bombing claimed the lives of 168 people. The Oklahoma City bombing was a domestic terrorist truck bombing on the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma, United States on April 19, 1995.  Perpetrated by Timothy McVeigh and Terry Nichols, the bombing killed 168 people, injured more than 680 others, and destroyed one-third of the building.  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 an estimated $652 million worth of damage.  Extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, and substantial donations were received from across the country.  The Federal Emergency Management Agency (FEMA) activated eleven of its Urban Search and Rescue Task Forces, consisting of 665 rescue workers who assisted in rescue and recovery operations.  The Oklahoma City bombing was the deadliest terrorist attack on American soil until the September 11 attacks six years later, and it still remains the deadliest incident of domestic terrorism in United States history.

Murrah Federal Building, which was destroyed in the Oklahoma City bombing on April 19, 1995. A variety of alternative theories have been proposed regarding the Oklahoma City bombing.  These theories reject all, or part of, the official government report.  Some of these theories focus on the possibility of additional, unindicted, co-conspirators or additional explosives planted inside the Murrah Federal building.  Other theories allege that government employees and officials, including US President Bill Clinton, knew of the impending bombing and intentionally failed to act on that knowledge.  Government investigations have been opened at various times to look into the theories.
