Two people were killed and 19 others injured when a small aircraft crashed into the rooftop of a commercial building near Fullerton Airport in California on Thursday, local police said.

Both fatalities were believed to be occupants of the four-passenger aircraft, which was found engulfed in flames inside the structure.

Identities of the deceased will be released later.

Of the 19 people injured inside the building, 11 were transported to local hospitals while eight were treated at the scene and released.

The US National Transportation Safety Board and Federal Aviation Administration are investigating the incident.
