On October 23, the FBI issued an intelligence update warning state and local law enforcement
of recent reporting that Al Qaeda is targeting the U.S. railway and petroleum sectors. Information from debriefings of Al Qaeda detainees as of mid-October indicates that the group has considered directly targeting U.S. passenger trains.
The U.S. Intelligence Community continues to assess that Al Qaeda plans to
attack targets that they believe would be readily recognized as representing
U.S. economic interests. Additional information suggests operatives may try a
variety of other attack strategies, such as destroying key rail bridges and
sections of track to cause derailments or targeting hazardous material
containers. Recently captured Al Qaeda photographs of U.S. railroad engines,
cars, and crossings heighten the intelligence community's concern of this
The attack of the French oil tanker off the coast of Yemen and additional
information from Al Qaeda detainees suggest plans exist to continue attacks
against the global petroleum sector. According to this information, Al Qaeda
plans to weaken the petroleum industry by conducting additional sea based

extensive operations against port facilities and other energy-related targets
including oil facilities and nuclear power plants.

threat reporting on such sectors as, the airline and maritime industries,
financial sector and government facilities and installations.

The Department of Energy's Office of Energy Assurance has contacted key
energy infrastructure facilities and is working with them to enhance the
security environment to deter and/or disrupt potential attacks.
The Environmental Protection Agency has contacted the American Chemistry
