After two explosions rocked the finish line of the Boston Marathon Monday, killing at least two and injuring dozens, California law enforcement and emergency officials are monitoring the situation and how it relates to California.

California's State Threat Assessment Center, which comprises the governor's office, California Highway Patrol, the California Emergency Management Agency and the California Department of Justice, is searching for ties to any activity in California.
"This event has got all of our fusion centers ... diligently combing through information and looking at the news reports," said Kelly Huston, the center's spokesman. "At this point there isn’t anything from Boston that’s relevant to California, but we continue to be looking."
Bay Area police departments are also on heightened alert.
In San Francisco, officers near critical infrastructure and in crowded areas such as Union Square, Fisherman's Wharf and Market Street are remaining "extra vigilant," said Officer Albie Esparza, spokesman for the San Francisco Police Department.
