No credible local threats to DC area following Brussels attacks

WASHINGTON - Law enforcement agencies in the D.C. area said they are monitoring the attacks in Brussels, but there are no credible local threats reported at this time.

Metro Transit Police said they are in touch with federal partners overseas after explosions rocked the Brussels airport and subway system Tuesday, resulting in numerous injuries and deaths. Metro's police chief met with the FBI to discuss law enforcement efforts in the wake of the attacks.

A tweet posted online said they have received no known threat to Metro. However, additional K-9 sweeps and patrols will be put into place Tuesday as precaution.

In a statement, the Metropolitan Washington Airports Authority said Reagan National Airport and Dulles International Airport have robust security, both visible and behind-the-scenes, and its priority is the safety and security of passengers and employees. The authority said it constantly trains workers and evaluates procedures with federal and local partners to make adjustments based on new information.

United Airlines said two of their flights to Brussels International Airport landed safely Tuesday morning. One of the flights departed from Dulles International Airport.

"We had two arrivals at Brussels International Airport this morning. Flight 950 from Washington Dulles arrived at 7:01 a.m. and customers deplaned normally at the gate. Our second flight - flight 999 from Newark Liberty - was rerouted to a remote location and our customers and crew have deplaned. All remaining flights to and from Brussels International have been suspended until further notice from local authorities."

D.C. officials said increased law enforcement have been activated.

"We look at all of what we think could be target areas and make sure that they have the resources and visibility that they need," said D.C. Mayor Muriel Bowser.

"I think for the general public, we will see an increase visibility in both uniform officers and cars and other equipment out," said D.C. Police Chief Cathy Lanier. "But there is a lot of things we do that are not visible to the public and are intended to not be visible to the public. I think that those are all forms of security."

Prince George's County police in Maryland said they are working with Metro Transit Police to help increase security presence at Metro stations and transit hubs in the county.

Amtrak said in a statement that they have deployed extra officers and are working with law enforcement about their security measures:

"Amtrak maintains a strong security posture to keep our passengers, employees and the railroad safe. Partnering with local, state and federal law enforcement, robust security measures are in place at stations, on trains and along the tracks. Amtrak Police are working with state, local and federal law enforcement partners to gather and share intelligence. Extra officers have been deployed. We have reminded Amtrak employees to look for and report any suspicious activity and unattended items and reissued guidance pertaining to facility inspections and active shooter incidents. Individuals are encouraged to report behaviors or activities that are unusual or out of the ordinary such as trespassers and suspicious packages by calling Amtrak Police at 1- 800- 331- 0008 or texting APD11 from a smartphone or 27311 from a standard cell phone."
