Terrorists May Use Scuba Divers, Planes
W A S H I N G T O N, May 24 — Terrorists may use scuba divers or small planes to attack targets in the United States, the FBI said today in the latest in a series of unconfirmed warnings.
"Recent information has determined that various terrorist elements have sought to develop an offensive scuba diver capability," the FBI said in an information bulletin issued by its National Infrastructure Protection Center.
"While there is no evidence of operational planning to utilize scuba divers to carry out attacks within the United States, there is a body of information showing the desire to obtain such capability," the FBI said.
Citing "uncorroborated information," the FBI also discussed possible terrorists using small planes.
"The interest is reportedly in the use of small aircraft, as opposed to large, commercial aircraft, due to post-September 11, 2001 enhancements in aviation security throughout the United States," the FBI and the Transportation Security Administration said in an alert to law enforcement.
The warnings are the latest in a string issued this week. Federal transportation officials said in an alert made public Thursday that they have gotten an unconfirmed warning that terrorists are planning attacks on subways in the United States.
The possible attack would involve simultaneous strikes against multiple trains, perhaps using time bombs, said an alert issued by the Department of Transportation's Office of Intelligence and Security and obtained by ABCNEWS.
Although the warning specified subways, it advised all rail and transit security officials to review their safety procedures and "implement additional security measures commensurate with the current threat environment."
It emphasized that the threat was not confirmed, but advised the industry to remain on a heightened state of alert.
The subway warning is particularly unsettling to New Yorkers, where millions of people ride the city's subways every day. Residents there were told this week that the Brooklyn Bridge or the Statue of Liberty could be targeted by terrorists.
And around the country, federal officials warned building managers to be on the lookout for terrorists trying to rent apartments for the purpose of planting explosives. Apartment building management companies sent copies of the warning to residents of some buildings in New York and Los Angeles earlier this week.
