Authorities were investigating why a private plane crashed early Thursday in San Diego, killing two people, damaging homes and igniting cars in the U.S. military's largest housing neighborhood.

Several people are believed to have died after a small plane crashed into a residential street in San Diego on Thursday morning.

“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.”
