Four people have been killed in a fire crash on a California highway that police say was likely caused by a wrong-way driver.

The horrific incident happened around 3 a.m. Sunday on the southbound lanes of Highway 71 in Chino Hills, officials said.

When officers arrived at the scene of the incident, they found at least one of the vehicles involved still engulfed in flames, NBC Los Angeles reported.

Four people died at the scene of the accident involving at least four vehicles. Officials say the victims, who have not yet been identified, were in two of the cars.

Another person was taken to hospital with unknown injuries. Southbound Highway 71 remains closed until further notice.

California Highway Patrol has not determined why the driver was heading the wrong way on the road in San Bernardino County, about 35 miles east of Los Angeles.
