Two people died and 18 others were injured after a small plane crashed into a commercial building in Southern California, officials say.

Ten people were hospitalized with injuries, Fullerton police said in a post on X Thursday afternoon. Eight other people were treated for their injuries and released at the scene.

According to the Federal Aviation Administration, the RV-10 single-engine van crashed at 2:15 p.m. PST (20:15 GMT).

The officials did not provide any further information about the accident. It is unclear whether the two people who died were workers or were on board the plane.

Police say they are evacuating buildings in the area and asking the public to stay away from the crash site.

Congressman Lou Correa, who represents the Orange County area, about 25 miles (40 km) south of Los Angeles, said the building hit was a furniture manufacturing company.

In a post on X, Correa said at least a dozen of the victims were factory workers.

Aerial photos of the scene show parts of the aircraft inside the building. The accident also caused a fire that was extinguished by the fire department.

According to local news outlets, security footage taken from a building across the street shows a fiery explosion.

“People are just shocked by the situation,” said witness Mark Anderson KRCA-TV.

“There was just a big bang, and then one of the people walked out and said, ‘Oh my God, the building is on fire.'”

The area where the plane crashed is near Fullerton Municipal Airport, about 10 kilometers from Disneyland.

According to KRCA-TV, the plane appears to have returned to the airport shortly after takeoff.

According to CBS, the BBC’s US affiliate, this is the second plane crash in the region in the past two months.

On Nov. 25, another plane crashed into a tree about a block from this most recent crash. No major Injuries were reported in this accident.
