() A small plane crashed into a San Diego neighborhood on Thursday, setting multiple homes on fire and causing evacuations.

The Cessna 550, which can carry six to eight passengers, crashed near the Montgomery-Gibbs Executive Airport around 3:45 a.m. Pacific time, according to the Federal Aviation Administration.

At the time of the crash, the weather was foggy.

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

He said “there is a direct hit to multiple homes” in the Murphy Canyon neighborhood and described “a gigantic debris field” in a dense, packed neighborhood.

It’s not known if there are injuries or fatalities connected to the crash at this time.

The National Transportation Safety Board will handle the investigation.
