FBI warns transportation, other industries

| 9/11/2002

Fearful of new terror attacks, the United States is urging heightened vigilance as Americans observe the first anniversary of September 11, the White House said Tuesday.

While officials say they have no details outlining an impending attack, they're taking no chances. White House Press Secretary Ari Fleischer said Tuesday the threat of new attacks has U.S. officials on a ``higher sense of guard.''

Meanwhile, the FBI told police, utilities, banks and the transportation industry to be wary. U.S. military bases and diplomatic missions worldwide also are on high security alert for the week.

In the past few days, U.S. intelligence agencies have detected what officials now describe as a marked increase in terrorist ``chatter,'' information from monitored communications and other sources that are used as a barometer of the likelihood of potential attacks.
