Extra Patrols At SFO, On BART In Wake Of Brussels Terror Attacks

SAN FRANCISCO (CBS SF) – Additional patrols will be in place at the San Francisco International Airport and on BART, after terrorists attacked the airport and a train station in Brussels, Belgium.

Doug Yakel, spokesperson for the San Francisco International Airport said passengers can "expect to immediately see heightened vigilance, in the form of increased patrols" around SFO.

Yakel said the airport will review this incident with TSA and law enforcement to determine if changes need to be made with passenger screening procedures.

The San Francisco Police Department has deployed extra officers at SFO, the Port of San Francisco, and at San Francisco Municipal Railway stations following the Brussels attacks, police spokesman Officer Albie Esparza said.

"We're asking the public if they see something, say something and to report any suspicious activity," Esparza said.

BART spokesperson Alicia Trost said there will be increased patrols, even though there is no credible threat to the transit system.

Oakland International Airport has also increased its visible security presence, according to airport spokeswoman Keonnis Taylor, although she said she couldn't talk specifically about any security measures.

At Mineta San Jose International Airport, spokesperson Rosemary Barnes said they have been in touch with the TSA, but they have not been given any direction to change security procedures where passengers will be impacted.

Long security lines were reported and the PreCheck line was closed Tuesday morning at SJC. Barnes said the long lines were due to TSA staffing issues and not because of the attacks.

Also in Santa Clara County, the Valley Transportation Authority said officers patrolling their system are on "heightened alert" and said they are "well prepared" for this type of threat.

Officials in Belgium said explosions went off at the airport in Brussels on Tuesday, killing 16 people. An hour later, an explosion at the Maelbeek Metro station killed 20 people.

Belgian media said at least one suicide bomber was behind the two explosions at the airport. ISIS has claimed responsibility for the attacks.
