An active shooter situation has been reported and confirmed by local authorities in San Bernardino, California. As many as 20 people have been shot, according to the Los Angeles Times. The shooting reportedly took place at Inland Regional Center, a facility for people with developmental disabilities. A banquet for "county personnel" was being held during the time of the shooting, KABC reports. President and CEO of the Inland Regional Center Marybeth Field confirmed the shooting happened in a "conference area" where a banquet was being held by the San Bernardino County Department of Public Health. Three suspects are believed to have "entered and started shooting" before leaving in a black SUV, with KABC reporting the vehicle was "possibly a GMC Yukon." Nearby courts and other buildings have been placed on lockdown, including schools.

During a press conference, Chief Jarrod Burguan confirmed that "up to three" shooters shot and killed 14 people and injured at least 14 others. That number has since increased to 17 injured. "These were people that came prepared to do what they did," Burguan told reporters, "as if they were on a mission." Police are urging people to "avoid the area" of Orange Show Road and Waterman Avenue and to remain alert. "At minimum we have a domestic terrorism incident that occurred here," Burguan told reporters, adding that the suspects used "long guns" and not handguns. Additional details regarding the attackers' weapons have not been released.

Though details regarding the shooting were not immediately known, photos across social media showed heavily armed police forces surrounding a neighborhood in San Bernardino. A father revealed to KABC that his daughter was inside the building when the shooting occurred, sharing a text message exchange in which she reportedly said "10 to 20 people" were shot, though these numbers have not been confirmed.

"We are not only using our SWAT team, but using SWAT teams from other jurisdictions to clear the facility," San Bernardino Police Lt. Richard Lawhead told KNBC during an interview. "As far as we know it’s confined to the Inland Regional Center." Loma Linda University Medical Center has entered "disaster mode," expecting a large influx of patients. At least six patients are being treated at Arrowhead Regional Medical Center, KABC reports. Local news outlets also captured images of people exiting an unidentified building, some with their hands up:

The local sheriff's office estimates "as many as three" total suspects and "multiple victims," according to the Washington Post. Fox News is also reporting that a "suspicious device" was discovered inside a building where one of the suspects was reportedly seen with "a ski mask and bulletproof vest." Though local authorities have not confirmed the total number or description of the suspects, Fox 11 says that police are searching for "three white males dressed in military gear." Authorities did not confirm these reports during the first press conference, though additional updates are expected "on the hour" for the duration of the active shooter incident.

The FBI is also assisting in the response, though local authorities will take the lead. The black SUV that was allegedly seen exiting the scene of the shooting was later claimed to have been found after reportedly being abandoned, according to a report from KTTV Fox 11's Araksya Karapetyan​. This report has also not been confirmed by law enforcement.

Shortly after news of the apparent mass shooting event broke, President Obama was reportedly briefed by his Homeland Security advisor before eventually giving a statement to CBS News. "We have a pattern now of mass shootings in this country that has no parallel anywhere else in the world," Obama said. "Our hearts go out to the victims and the families." Obama also called for greater and more unified gun control reform, citing the increasing prevalence of this type of tragedy:
