The Federal Aviation Administration today advised all U.S. airlines and airport officials to be "extra vigilant" for possible terrorist attacks as a result of the U.S. bombings of Libya.
FAA officials said the agency also is requiring all U.S. airlines that operate into foreign airports to take "special additional security measures."
FAA spokesman Fred Farrar said the agency would not elaborate on what additional measures the airlines must take.
U.S. airlines operating in certain parts of the world where the terrorist threat has been highest have been required since last summer to take special precautions in checking baggage. Those precautions were ordered after the hijacking of a TWA jetliner last summer.
