At least 14 people are dead after a shooting in San Bernardino, California — about 60 miles east of Los Angeles.
The shooting happened at the Inland Regional Center, a county agency that provides services to the disabled.
San Bernardino Police Chief Jarrod Burguan told reporters that at least 14 people are dead and 17 more were injured in the shooting, which police responded to at about 11 a.m. local time, according to emergency officials.
"They came prepared to do what they did as if they were on a mission. They came in with a purpose," Burguan added, noting that the shooters were armed with long guns rather than hand guns. "They came in with the intent to do something."
One of the three suspects has been identified as Syed R. Farook, the LA Times reported, citing two law enforcement sources. The Associated Press has also cited law enforcement sourcesidentifying Farook as a suspect.
According to the LA Times report, an exchange was "overheard on a law enforcement radio channel" in which an official could be heard telling a dispatcher Farook "was at the meeting" at the Inland Regional Center and "was acting nervous" then "left out of the blue," minutes before gunfire began.
The suspects' vehicle had been described as a dark-colored SUV.
A police chase began and ended in a shootout involving San Bernardino Police. A dark-colored Ford Expedition could be seen in the street, windows shattered, less than 2 miles from the scene of the mass shooting.

A third person who ran away from that scene has been detained, according to David Bowdich with the FBI's Los Angeles bureau. It wasn't clear whether that person was involved.
Both of the dead suspects were armed with "assault-style weapons" and handguns, law enforcement officials report.

The LA Times interviewed an unnamed man whose relative works at the Inland Regional Center.
"It was a pretty horrifying phone call to get from a family member that is hiding in an office because there is an active shooting taking place," the man said. "This is wrong. Why would they target an agency that deals with helping handicapped people?"
US President Barack Obama was briefed on the shooting by US Homeland Security Adviser Lisa Monaco, later telling CBS that "We should never think that this is something that just happens."
