Allegations of Iraqi mobile weapons laboratories

During the lead-up to the Iraq War, the United States had alleged that Iraq owned bioreactors, and other processing equipment to manufacture and process biological weapons that can be moved from location to location either by train or vehicle. Subsequent investigations failed to find any evidence of Iraq having access to a mobile weapons lab.

In the run up to the 2003 Invasion of Iraq, the main rationale for the Iraq War were allegations that Iraq had failed to transparently and verifiably cease their weapons of mass destruction (WMD) program. In February 2003, Secretary of State Colin Powell gave a presentation before the United Nations showing a computer image of what were purported to be mobile weapons for creating biological agents. He said Iraq had as many as 18 mobile facilities for making anthrax and botulinum toxin, stating "they can produce enough dry, biological agent in a single month to kill thousands upon thousands of people." Powell based the assertion on accounts of at least four Iraqi defectors, including a chemical engineer who supervised one of the facilities and been present during production runs of a biological agent. Following the invasion of Iraq two trailers were found and initially described as the alleged mobile labs.
