Bay City News and Patch Staff Reports —

Updated 12:45 p.m. Tuesday: The San Francisco Police Department has increased its patrols of the San Francisco International Airport as part of a 48-hour high alert, according to Lily Wang, airport duty manager. Police patrols cover the public area of the airport, the area behind security checkpoints and the airport perimeter, Wang said.

Updated 9:07 a.m. Tuesday: With the Bay Area's own historic road race just a month away, Bay to Breakers officials issued this statement on their Facebook page:

Our thoughts and prayers go out to the victims of the tragic events that took place during today’s Boston Marathon. The safety and security of our participants and spectators will continue to be our first priority. In the coming days we will work closely with the 
SFPD and City of San Francisco to assess and update our plans as information develops.

Runners responded with emphatic support for the race, set for May 19, begging organizers to not respond to fear and suggesting that racers honor the Boston terror attack by running in Boston T-shirts or Beantown colors of orange, green and white.

"We need to continue to run and live our lives regardless of those who want us not to. Let's show them how strong we are by pounding the pavement and continuing to make the strides that we, as a nation, have been doing for centuries," one poster said.

In fact, local running clubs and athletic stores, such as this one in Saratoga, are organizing get-togethers to just go for a run in support of marathoners.

Updated 8:07 a.m. Tuesday: An Alamo man who had just crossed the finish line when the bombs exploded describes the scene as "horrific."

Stan Rowland, 60, an attorney running the historic race for the first time, said he heard a sound like he'd never heard before a block or two away and turned and saw smoke rising from the marathon route.

As of Tuesday morning the tally of those injured had risen to 176, including an East Bay boy, 12.

Updated 7:34 p.m. Monday: The son of a Martinez woman who was running the Boston Marathon was among the more than 130 wounded in the bomb blasts, according to Martinez Patch readers.

The boy underwent surgery, and his injuries are reportedly not life-threatening.

Meanwhile, security measures are being tightened for at least two local sporting events Monday night in light of today's bombing in Boston.

Two bombs exploded at the finish line of the Boston Marathon shortly before 3 p.m. Boston time, killing at least two people and hospitalizing dozens.

The events have put everyone on alert, and Oakland police said they plan to have a beefed-up presence at tonight's Oakland Athletics and Golden State Warriors games at O.co Coliseum and the Oracle Arena. The A's are hosting the Houston Astros at 7:05 p.m. on Jackie Robinson Day, a day to memorialize the Hall of Famer. The Warriors are taking on the San Antonio Spurs at 7:30 p.m.

"We will have a more visible presence than normal at our major sporting events this evening, and are coordinating collaboration for enhanced security measures or needs with the BART Police Department, Alameda County Sheriff's Department, and local commuter ferry services," Oakland police said.

The San Francisco Giants, who do not return home until Friday, will continue to prioritize safety at AT&T Park, a team spokeswoman said. "Security is always our number-one priority," Giants spokeswoman Staci Slaughter said. "When something like this happens, it's just an unfortunate reminder of how important it is."

Meanwhile, BART is monitoring the situation in Boston and has not received any information to suggest it is a potential target, spokeswoman Alicia Trost said.

The San Francisco Municipal Transportation Agency is working with San Francisco police to increase security throughout the system and its facilities, spokesman Paul Rose said.

Updated 2 p.m. Monday: Flights to Boston are being delayed, according to the FAA website, following Monday's explosions at the Boston Marathon, which has put Bay Area police on heightened alerts.

This is causing some delays out of San Francisco International Airport. (Check this website for flight status information.)

San Francisco police were on heightened alert, a police spokesman said.

San Francisco police spokesman Officer Albie Esparza said the department has increased patrols around the city's "higher-profile potential targets," and in areas where there are large crowds. Police are asking members of the public to be especially vigilant and report any suspicious activity by calling 911.

There was no heightened security at Bay Area airports as of 1:15 p.m., though reports indicate that flights have been temporarily restricted in the Boston area.

San Francisco International Airport spokesman Doug Yakel said the airport is waiting for direction from the Transportation Security Administration.

"The TSA typically leads the way on that, and if there's any changes that need to be made to our security procedures, they would communicate that out," he said.

Golden Gate Bridge spokeswoman Mary Currie said normal security procedures are in place along the span, but that bridge district officials are "aware of the situation" and are in communication with partner agencies to ensure safety.
