UPDATE: The victims have been identified.

Four people were killed and several others were injured in a crash Friday morning on U.S. 30, troopers say.

The Oregon State Police said the driver of a minivan with seven passengers tried to turn left off the highway onto a Clatsop County road. The van was hit by an oncoming Ford F-450 that was towing an empty horse trailer.

Four people in the van died, three were flown to Portland hospitals and one was taken to a local hospital in an ambulance, troopers said. Three people from the truck were taken by ambulance to local hospitals.

None of them have been publicly identified.

The Oregon Department of Transportation said Friday afternoon that the highway had reopened in both directions after a closure about 14 miles west of Clatskanie. Traffic is being flagged through the area in the highway's westbound lane, the agency said.

The Oregon State Police said the crash is under investigation.
