A small plane crashed Thursday morning into a San Diego neighborhood amid foggy weather, spewing jet fuel and setting over a dozen homes on fire, according to news reports.

The Federal Aviation Administration says the Cessna 550 aircraft crashed in the Murphy Canyon neighborhood, near the Montgomery-Gibbs Executive Airport.

“We have jet fuel all over the place,” Assistant Fire Department Chief Dan Eddy said during a news conference, according to the Associated Press. “Our main goal is to search all these homes and get everybody out right now.”

The plane can carry six to eight people, but the FAA said the number onboard is unknown.
