• This concludes our live coverage. We will continue following this story on bbc.co.uk/news and on BBC World News.

There were two people in the vehicle, now both dead, police say, a third person was running away, may or may not be involved but in custody.

The third suspect is separate from the person in custody.

FBI agent says he does not know "the disposition" of the third suspect.

The Los Angeles Times and the New York Times, citing unnamed law enforcement officials, say investigators believe the suspects were known to those targeted

"Investigators believe there were three gunmen and one of them had worked at the facility and recently had a dispute with fellow employees, according to law enforcement officials," the New York Times reports, adding a witness said despite a face covering, one sounded and appeared very similar to employee who had left earlier.

Loma Linda University Medical Center says they received five adult patients - two critical but stable, two fair, one still being assessed. 

The hospital was put on alert for an hour after a bomb threat but it has been cleared.

David Danelski, a staff writer with the Press Enterprise, has sent his colleagues a dispatch from a neighbourhood backyard as police searched for a suspect.

More cops come and one officer starts yelling at me and pulls his pistol and he asks me what I’m doing there.

“I’m a reporter,” I said.

“How did you end up here?” the cop asks.

“I just got caught up in this,” I told him.

He said, “We don’t know who’s out here. Take your camera and go.”

Reuters captured families as they reunited with loved ones returning from the scene of the shooting

The San Bernardino County Department of Public Health has confirmed to the AP that several of its employees were inside a social services facility when gunmen opened fire.

Aerial footage now shows police searching house by house in the neighbourhood where the vehicle was stopped.

A San Bernardino police spokeswoman said an officer was injured but did not suffer life-threatening wounds after police spotted the vehicle in a nearby neighbourhood. 

"A suspect has been hit," she says, but it is unclear if there is still one or two suspects at large.

After the mass shooting in San Bernardino, Governor Edmund G. Brown Jr. issued the following statement:"Our thoughts and prayers are with the victims' families and everyone affected by the brutal attack. California will spare no effort in bringing these killers to justice." 

Despite being shot three times, Kevin Ortiz called his wife and father to tell them he was alive, reports the Los Angeles Times.

Ortiz was shot twice in the leg and once in the shoulder during an attack at Inland Regional Center in San Bernardino.

Kevin said he had been shot three times and that he was in pain but he was all right. Then he said ‘I love you’ and I said ‘I love you.’

The New York Times speaks to one resident of the street where police have surrounded a dark vehicle with three armoured cars.

"It’s two blocks from my house. I can’t go outside. Some guy told me, get inside, lock your doors," Linda Pevlor says.

The Huffington Post looks at what police ask residents to do during a manhunt.

Police were involved in a shootout with a black SVU and said one suspect was down

• Number of wounded has increased to 17, number of deceased is 14
• At a second scene, there were shots fired, officers were involved and a suspect is down.
• All officers are "OK," but unclear whether any officers were hurt
• Injuries range from minor to gunshot wounds

The BBC's James Cook in San Bernardino says that there are no initial indications that events in the town are linked to Islamist violence, but points out that the situation is still very fluid.

Throughout his presidency Barack Obama has often had to address the US after mass shootings.

As the years passed, his calls for stricter gun control grew louder, and pushback from his opponents grew stronger.

So how did this translate into the words he used to comfort the nation after such attacks?

Earlier this year, the BBC contrasted his language with levels of gun ownership during his terms in office.

"We have suspects at large but we have absolutely no idea where they are," San Bernardino police spokeswoman Vicki Cervantes is quoted by Reuters as saying. 

Comments from Chief Burguan, San Bernadino police: "We know a lot of people are very worried about their loved ones. We have set up a centre where family members can go for information. We also have a hot line number people can call if they have any info.

"I've heard everything from the fact that it was a meeting, to a holiday event - I dont know for sure what the case is but I know most of the victims were concentrated in one area."

Mr Burguan said he no information that children were involved and preliminary information indicates "that these were people who came prepared". 

The Washington Post built a map to show incidents in which four or more people were injured or killed by gunfire in 2015.

The author explains, the yellow circle is San Bernardino (with unconfirmed reports of the victims so far); the blue circles are those in which people were killed; outlined circles are the number injured.

There have been mass shooting incidents in 46 states and in DC Florida, Illinois and California have had the most incidents. In each state, there have been at least 22 shooting incidents in which four or more people were shot.

During the press conference, police said they believed the suspects were not using handgun, i.e. short, hand-held guns but "long guns". A police spokesman refused to specify further, meaning the weapons used could be anything from a hunting rifle to assault-style weapons

The shooting took place at the Inland Regional Center, one of 21 facilities set up by the state and run under contract by non-profit organizations to serve people with developmental disabilities, said Nancy Lungren, spokeswoman for the California Department of Developmental Services. According to Alex Vasquez, a videographer an NBC affiliate, the IRC is always busy.

"This is a center that is always full at all hours of the day, so I can just imagine there must have been a lot of people in that building. Sometimes I've been here where the line is even outside," he said.

The facility offers specific programs designed for age groups: 0 to 3-years-old; 3 to 15; 16 to 22; 23 to 59; and adults over 60.  

• Up to 14 dead, 14 injuries

• Building is massive, still clearing the scene

• Several hundred people in the building who were not injured have been evacuated

• Have set up an area for family members to go for information

• up to three people entered the building and began shooting

• Suspects may have fled the area

• shut down the courts and city buildings in the area, increased police presence in the area, including at hospitals

• Suspects at large
• Police confirm suspects had long guns, preliminary reports show "they came prepared"
• FBI - "We do not know if this is a terrorist incident"

We have a pattern now of mass shootings in this country that has no parallel anywhere else in the world

The Sheriff's office has scheduled a news conference within several minutes time.

Earlier this year, the Los Angeles Times featured San Bernardino in a lengthy article about the rise and fall of the city.

"San Bernardino, once a sturdy, middle class "All-America City," is now bankrupt, the poorest city of its size in California, and a symbol of the nation's worst urban woes."

Speaking on CNN, Lavinia Johnson said the centre had been rented out for a county employee holiday event.

Her staff began to exit when they heard a fire alarm but got an active shooter message and went back into the building and locked themselves in their offices.

According to the Washington Post, one person was killed and three were injured in a shooting much earlier in Georgia.

"We don't know where those shooters are," police Sgt Vicki Cervantes says. "They are heavily armed and they are possibly wearing body armour, things of that nature. It is not a safe area to be, it's very dangerous. The fewer innocent people we have in here, the better"

Terry Petit told reporters that his daughter works at the center, and he got a text from her saying she was hiding in the building after hearing gunshots. Petit choked back tears as he read the texts for reporters outside the center. He said she wrote: ``People shot. In the office waiting for cops. Pray for us. I am locked in an office.'' 

The president and CEO of the Southern California social services centre where gunfire has erupted says the focus is on a building that houses at least 25 employees as well as a library and conference center, AP reports. 

Police are now searching for an SUV that fled the scene of a mass shooting that left up to 20 people injured inside of a social services building in San Bernadino, federal law enforcement sources told the Los Angeles Times.

At least three suspected shooters vanished from the building after the gunfire, the source said. Police have also used a robot to detonate a suspicious device found on the premises, according to the sources, who requested anonymity because the investigation is active and ongoing.

Police on the scene were assembling a battering ram to gain access to the building, and investigators may believe one suspect was still inside, the source said.

President Barack Obama has been briefed by Homeland Security Adviser Lisa Monaco about the shooting in San Bernardino and has asked to be updated on the situation as it develops, according to the White House pool report
