14 people were killed and at least 17 were injured in a mass shooting in San Bernardino at the Inland Regional Center today. Police say upwards of three shooters were involved. Two of those suspects were killed after a standoff with police hours after the shooting, but the third suspect is still running through a neighborhood near San Barnardino Avenue. One suspect is down and police are still actively pursuing the other shooters who killed at least fourteen people in San Bernardino today.

One suspect is dead, a second suspect is in the back of a dark SUV on San Bernardino Avenue that's currently surrounded by SWAT cars, and police may be looking for a third suspect that fled in the neighborhood.

SWAT cars surrounded and shot up a dark SUV on the south side of San Bernardino Avenue while others may be searching for a third suspect. Police also say they may have found a pipe bomb near the shooting location.

One San Bernardino officer was injured but did not suffer life-threatening injuries.

Officers say there are as many as three suspects on the loose, and the San Bernardino Sheriff said a holiday party with government officials present was happening in the complex during the shooting. The social services center where the shooting occurred serves people with developmental disabilities in the area.

Police and ambulance vehicles flood roads near the shooting. Officials called the shooting an act of domestic terrorism, but said they don't know if the shooters had a motive. The Sheriff also said the shooting was heavily premeditated, adding that the suspects "were on a mission" and heavily armed. Shooters came prepared, potentially dressed in military style clothing and potentially wore masks.

Police have shut down the area near the social services center while they are looking for the shooters.

President Obama has been briefed about the shooting. No additional gunshots have been heard in the area, but we still don't know if any shooters are still active in the building.

The facility is very large, so officials are saying it will take time to search the three building complex for any potential suspects or any other victims.

We will continue to update this story as more details come in.
