The FBI has launched a full-scale investigation to determine the scope and origin of the recent terrorist attack, and said that numerous terrorist threats have been reported since September 11, including unconfirmed reports regarding the potential use of chemical, biological, and/or radiological/nuclear WMD.
"Representatives at recipient facilities, particularly those that manufacture, distribute, transport or store hazardous chemicals, should be especially vigilant,” FBI said in a press release. “Any suspicious activity, including threats, unusual purchases, suspicious behavior by employees or customers, etc., should be expeditiously reported to the local FBI field office.”
FBI said its offices, through its WMD coordinator, will facilitate a formal threat assessment process with FBI Headquarters and other government agencies as necessary. U.S. DOT & state and local recipients should also be advised to take appropriate precautions regarding any transport of hazardous chemicals and/or WMD precursors and note any similar suspicious activity. Any pertinent information should be provided to the local FBI field office, the agency said.
FBI and the U.S. DOT said they have no information of any specific threats directed against additional targets; however, they said the U.S. transportation industry should remain at a heightened state of alert and should implement security measures commensurate with this level of security.
