A small plane crashed in Santee, California, near San Diego, fully engulfing at least one home in flames, Santee Fire Chief John Garlow said.

There are at least two burn victims who are believed to be from the home, Garlow said.

The FAA said the twin engine Cessna C340 crashed at 12:14 p.m. local time. It’s not yet clear how many people were on board.

The plane also hit a UPS box truck and knocked out a hydrant, Garlow said.
