(AP) -- California officials from San Diego to the San Francisco Bay area are calling for increased vigilance at major sporting events and other gathering places in response to deadly explosions at the finish line of the Boston Marathon.
Acting Gov. Gavin Newsom says there's no indication of any threats to California. But he says the events are a reminder to remain vigilant and report anything unusual to law enforcement agencies.
The California Emergency Management System's assistant secretary says there's no known California connection to the explosions in Boston.
The San Francisco Police Department is on heightened alert and will be rethinking security logistics for the upcoming San Francisco Marathon and Bay to Breakers foot races.
Airports in Los Angeles, Van Nuys and Ontario are in a heightened state of vigilance with increased patrols.
