Still from video shows rescue crews tending to the injured in the intersection outside the Inland Regional Center in San BernardinoSAN BERNARDINO, Calif. (AP) – Police say they are searching for one or more gunmen after a shooting at a social services facility in Southern California.

Police say multiple people were shot at the Inland Regional Center in San Bernardino, a facility that serves individuals with developmental disabilities in Riverside and San Bernardino counties.

Several law enforcement agencies have converged on the scene, and triage units have been being set up in the area. Some people were seen being wheeled away on gurneys, and others filed out of a building with their hands up.

No arrests have been made.

San Bernardino is about 60 miles east of Los Angeles.

The head of the Inland Regional Center says “the incident is in the conference area” that an outside group had been renting, but people served by the center also would have been in the building.

The White House says President Barack Obama has been briefed on the situation.
