From Los Angeles International Airport to Dodger Stadium, L.A. officials said they will be on heightened alert because of the Boston explosions.

LAX officials said they are increasing patrols, beefing up checkpoints and using more bomb-sniffing dogs.

"While there is no information to suggest that there is any nexus to the Los Angeles area, in an abundance of caution, Airport Police has increased its presence at LAX, LA/Ontario International and Van Nuys airports by deploying bomb-detection canines, additional patrol officers and security personnel," L.A. World Airports said in a statement.

"Our thoughts and prayers are with the people in Boston in the aftermath of this senseless tragedy," Mayor Antonio Villaraigosa said in a statement. "We are working closely with our law enforcement partners to monitor the situation and stand ready to aid Boston in any way possible. The LAPD and other public safety agencies will remain vigilant at all public and sporting events in Los Angeles."

California's Acting Gov. Gavin Newsom released a statement saying "these events are a reminder to remain vigilant and always report anything unusual to your local law enforcement agency."
