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

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

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
