A gunman has taken three people hostage at a California veterans home.
Law enforcement authorities from multiple agencies responded to a report in the morning of shots being fired at the Yountville Veterans Home in Napa County, working to clear buildings and establish a perimeter.
A sheriff's deputy exchanged gunfire with the assailant, a California Highway Patrol spokesman said. The suspect released some people before retreating into a room with three hostages, all of whom were employees of a programme called the Pathway Home that works with veterans of the conflicts in Iraq and Afghanistan.
There were no reported injuries. As of the mid-afternoon, authorities had not yet made contact with the shooter after attempting to reach him via cellphone and phones inside the facility.
“We have quite a few hostage negotiators working for a peaceful resolution to this”, Napa Sheriff John Robertson told reporters, adding that he did not yet know what the suspect's potential motivation was.
Authorities said they had identified the shooter but were not yet releasing his name. They said he was believed to have used a rifle but did not identify the model.
A man named Larry Kamer, who said his wife worked as fundraiser for Pathway Home, told multiple news outlets that the gunman entered a going-away party before seizing hostages.
Napa County Sheriff's officials directed people to avoid the area. The California Highway Patrol said it had deployed officers and a SWAT team to the scene.
Video from the scene showed an armoured vehicle joining police cars in surrounding the facility.
The facility is America's largest veteran's home, according to California, housing some 1,000 people.
Yountville sits in the heart of California wine country, an area known for fine wine and upscale restaurants.
