A fire in a tanker truck in California has killed at least four people and left the area littered with charred wreckage, authorities said.
Authorities have not yet determined whether the tanker was involved in the crash that killed two people on Wednesday and left at least seven others injured.
Authorities said the fire broke out in the tanker truck’s rear-end and spilled fuel onto the road, sending the truck into a steep embankment in San Bernardino County, about 30 miles southwest of Los Angeles.
The truck was partially engulfed in fire, according to the Los Angeles Fire Department.
The cause of the blaze is under investigation, the fire department said.
No passengers were aboard the truck.
The blaze is in the town of Ojai, about 60 miles northeast of San Diego.
The highway was closed until Wednesday afternoon while authorities investigated.
Fire officials said a tanker fire in California killed two on Wednesday, a fire department official said.
The tanker truck was transporting diesel fuel from a refinery in Bakersfield to a gas station in the San Bernardino area, said the official, who was not authorized to discuss the investigation.
Authorities did not immediately release details about the passengers or cause of death.
The tanker was transporting a combination of oil and gas and was being used to fill an old tank at the nearby Chevron refinery, the official said, adding that the fire began in the rear of the tanker.
Chevron has not yet released the number of casualties.
The truck is owned by Gasparilla Energy Corp., according to its website.
Gasparilla did not respond to messages seeking comment.
