Multiple people on board a private plane that crashed into a San Diego military housing neighborhood early Thursday are dead but no one on the ground was injured, authorities said.

A small plane crashed into a San Diego neighborhood during foggy weather early Thursday, setting about 15 homes fire and evacuating homes along several blocks, authorities said.

“We have jet fuel all over the place,” Dan Eddy, San Diego’s assistant fire chief, said at an early morning news conference. He described the neighborhood as a “gigantic debris field.”
