A pre-dawn explosion and fire leveled a home, injured one person, and damaged at least two others Wednesday in Victorville, authorities said.

The blast occurred shortly before 3 a.m. (1000GMT) in the San Bernardino County desert community.

Victorville is about an hour’s drive northeast of Los Angeles.

A woman with burns was airlifted to a trauma center but there was no immediate word on her condition, authorities said.

Neighbors told local media that the family that lived in the home breeds dogs. An injured dog was taken away by animal control officers.

At least two damaged homes were red-tagged because they were considered unsafe for people to stay there, firefighters said.

The cause of the blast was under investigation.
