Police say at least 14 people have been killed in a mass shooting in Southern California. And another 14 are wounded.
The attack happened in San Bernardino at a training center for disabled people.
San Bernardino police chief Jarrod Burguan spoke to reporters after the incident. He said it is believed that three gunmen were involved. He said the shooters apparently fled the area. The numbers of casualities may change and it is not known if the shooting was a terrorist attack.
Burguan said there was a massive response to the shooting. He said several local and state security forces took part.
Earlier reports said the shooters may have been dressed in military clothing. A police spokeswoman told the Los Angeles Times that the attackers were heavily armed and possibly wore body armor.
A bomb squad reportedly was deployed to try to disarm a possible explosive device.
This latest shooting comes less than a week after a gunman killed three people and wounded nine in an attack at a family planning and health clinic in Colorado Springs, Colorado.
In October, a gunman killed nine people at a college in Oregon. In June, a gunman killed nine people at a church in South Carolina.
