Agencies Warn of Lone Terrorists
The possibility of war with Iraq could unleash acts of anti-American violence in the United States or overseas by individual extremists who do not belong to Al Qaeda or other Middle Eastern terrorist groups but sympathize with their grievances, intelligence and law enforcement officials say.

A classified F.B.I. intelligence bulletin, issued on Wednesday to state and local law enforcement agencies throughout the country, warned the authorities to be on the alert for lone terrorists who are not directed by organizations like Al Qaeda.

"Lone extremists represent an ongoing terrorist threat in the United States," the bulletin said. "Lone extremists may operate independently or on the fringes of established extremist groups, either alone or with one or two accomplices."

The officials said a war would inflame anti-American sentiment throughout the Arab world, adding to a litany of causes that have stoked hatred of the United States. One of the main issues expressed by many Arabs is their belief that the United States has supported Israel in its effort to put down the Palestinian intifada, or uprising. And some people may decide to strike against American targets almost on the spur of the moment, officials warned.

Moreover, analysts regard the new taped message believed to be from Osama bin Laden as a summons to his followers, and perhaps to new sympathizers, to conduct actions against the American targets in response to the possible war in Iraq.

Counterterrorism officials have long feared that a solitary terrorist with an automatic weapon or one committed to a suicide bombing could inflict heavy casualties in the United States.

The threat posed by what officials refer to as "lone wolves" who suddenly decide to act because of their increasingly radicalized views toward the United States is a major concern for American officials because their actions are difficult to predict or prevent.

"Many lone extremists have no links to conventional terrorist groups," the bulletin of the Federal Bureau of Investigation said. "In fact, F.B.I. analysis suggests that psychological abnormalities, as much as devotion to an ideology, drive lone extremists to commit violent acts."

Robert S. Mueller III, the bureau director, cited the threat of lone extremists in testimony last week to the Senate Intelligence and Armed Services Committees.

"The threat from single individuals sympathetic or affiliated with Al Qaeda, acting without external support or surrounding conspiracies, is increasing, in part because of heightened publicity surrounding recent events such as the October 2002 Washington area sniper attacks and the anthrax letter attacks," Mr. Mueller said.

One case cited in the F.B.I. bulletin was that of Hesham Mohamed Ali Hadayet, an Egyptian immigrant who fatally shot two people at El Al Airlines' ticket counter at Los Angeles International Airport in July 2002. While there are indications that Mr. Hadayet had connections to terrorists, the F.B.I. says it believes he acted alone.

American counterterrorism officials who have studied the nature of the threat from extremist Islamic terrorist groups said that they now realized they must distinguish between intricate plots that are carefully coordinated by groups like Al Qaeda and the less organized actions of individuals on the fringes of extremist movements.

The F.B.I. bulletin cited other examples of people who had engaged in the kind of violence that has worried counterterrorism officials. One was Timothy J. McVeigh, who was executed for the 1995 bombing of the federal building in Oklahoma City. Mr. McVeigh began plotting the bombing after a Michigan militia group distanced itself from him because "it became apparent that his views were too radical," the bulletin said.

Another solitary extremist identified in the F.B.I. bulletin was Paul J. Hill, an anti-abortion militant who fatally shot an abortion doctor and his assistant in Pensacola, Fla., in 1994.
