No Known Threats In Pa. After Brussels Attacks, Security Increased Across Region

Authorities across the region are stepping up anti-terrorism security measures in the wake of attacks that killed at least 26 people in Brussels.

Meanwhile, Pennsylvania Governor Tom Wolf said there is "no known related threats" in Pennsylvania.

Wolf said he spoke this morning with Director of Homeland Security Marcus Brown, who has been briefed by federal officials on the evolving situation in Europe.

"The Pennsylvania State Police and Office of Homeland Security are in communication with federal law enforcement partners regarding the attacks in Belgium and are continuing to monitor the situation for any changes," he said in a statement.

Scott Ladd, a Port Authority of New York and New Jersey spokesman, said Port Authority Police are increasing their anti-terrorism presence at Newark Liberty, JFK and LaGuardia airports.

At Philadelphia International Airport, a flight scheduled to arrive Tuesday from Belgium (American Airlines Flight 751) has been cancelled. An American Airlines flight that departed from Philadelphia International Airport and arrived at in Brussels Tuesday morning was not impacted by the attacks, airline officials confirmed.

"At this time, all of our airport employees and crew members are safe and accounted for with no reported injuries," a statement from the airline said.

A NJ Transit spokesman said his agency would discuss the matter sometime Tuesday.

Two blasts hit Zaventem airport Tuesday, killing 11 and injuring 81, the health minister said. Another explosion struck Maelbeek metro station an hour later in the Belgium city, killing 15 more, according to the New York Times.

The New York City Police Department is also closely monitoring the situation in Belgium and is "in close contact with our international partners and with the FBI."

"At this time, there is no known indication that the attack has any nexus to New York City. We will continue to follow the situation in Belgium closely with the Joint Terrorism Task Force and the FBI and adjust the department’s deployments accordingly," department spokesman Stephen P. Davis said.

Facebook has also activated a safey-check feature that tells family and friends of someone who may be impacted by an attack that they are safe.
