At least 14 people were killed Wednesday after a mass shooting at a San Bernardino, Calif., facility for people with developmental disabilities, CNN reports. More were injured, and police are actively searching for suspects.

Around 11 a.m., San Bernardino authorities first got a 911 call reporting shots fired around at the Inland Regional Center. The suspects, believed to be three men, were wearing body armor and armed with AK-47-type weapons and possibly other automatic types of weaponry. Enforcement agencies including a SWAT team worked to clear the building, and a bomb squad found a suspicious package on the center's second floor.

The total number of causalities remains unconfirmed. Police are searching for a black SUV that drove away from the scene.

Inland Regional Center employs nearly 670 people and serves more than 30,200. San Bernardino, a city of just over 200,000 people, is 60 miles east of Los Angeles.
