Page "Oklahoma City bombing" Paragraph 23

Initially, the FBI had three hypotheses regarding who might have been responsible for the bombing.

The first was international terrorists, possibly the same group that had carried out the World Trade Center bombing two years earlier.

The FBI also thought that a drug cartel might have been carrying out an act of vengeance against DEA agents as the building held a DEA office.

The last hypothesis was that the bombing was done by Christian fascists acting on conspiracy theories.
