ABSTRACT
Although terrorist groups have to date failed to successfully deploy a radiological weapon, they have attempted to acquire, and in a few cases have successfully deployed, chemical and biological weapons. For instance, in 1995, members of the Aum Shinrikyo religious cult carried out five coordinated chemical attacks in Tokyo, Japan. The group dropped plastic bags filled with sarin solution, punctured to allow the agent to leak and vaporize into train cars and station platforms.
