Federal officials said there were no immediate specific threats to the US after the death of Osama bin Laden. But some airports and local security officials said they were on heightened alert.

Airports and other potential targets of terrorist attack operated Monday in a state of heightened vigilance following the death of Al Qaeda leader Osama bin Laden in a Pakistan firefight with US Navy forces.

Despite concern about possible efforts to retaliate by Al Qaeda or groups aligned with the terror organization, security officials also sought to encourage a business-as-usual atmosphere.

The result was a mixed message, with some airports or municipal security agencies emphasizing that they were not taking unusual procedures, and others saying they were on heightened alert.

John Brennan, the top counterterrorism adviser to President Obama, said the US government knew of no immediate specific threats.

In the US, the Transportation Security Administration issued a low-key advisory, including this statement: "As always, passengers may notice a variety of security measures at US airports to include the use of physical bag checks, random gate screening, explosives-detection technology, canine teams, and behavior detection officers."

The statement asked travelers to report any suspicious activity to authorities, and Mr. Brennan said US security agencies would ramp up their vigilance against possible attacks.

New York City authorities briefly shut down a street in Times Square after investigating a suspicious package Monday which turned out not to be dangerous, the city's fire department said.

Philadelphia police stepped up patrols at places like transit hubs and religious sites, authorities there said.

• Similarly, police in Los Angeles increased patrols at possible terrorist targets and watched for hate crimes in the wake of Mr. bin Laden's death.

• A Port of Seattle spokeswoman says Sea-Tac Airport was not under heightened security Monday.

In Europe, embassies and some tourist sites saw extra security.

Denmark's intelligence agency warned about possible backlash attacks, although it said they are likely to be executed by individual and smaller groups outside Europe, especially in Pakistan.

"For militant Islamists, there will be prestige in being the first to avenge him and demonstrate that Islamic militants continue to operate," it said in a terror assessment Monday. "It is [our] assessment that the threat will be especially directed against US interests."

In Germany, which had arrested three suspected Al Qaeda members Friday on suspicion of making a shrapnel-laden bomb to attack a crowded place, there was no visible beefing up of security.

Interior Minister Hans-Peter Friedrich predicted the death of bin Laden will weaken terrorism in the medium to long-term. "[But] we must be clear that terrorist cells working in Europe and beyond exist very autonomously, will continue to exist, and we still have a high threat level in Germany and Europe."
