KANOSH, Utah: At least eight people were killed and ten injured in a 20-vehicle collision caused by a sandstorm Sunday afternoon, the Utah Highway Patrol said.

The vehicles crashed on Interstate 15 near the town of Kanosh. Ground and air ambulances were used to transport crash victims to local hospitals, where some are listed in critical condition.

The vehicles crashed into each other when high winds caused a sandstorm which reduced visibility, the highway patrol said.

Five of the eight people killed were in one vehicle, and two were in another vehicle. There are children among the dead, according to Highway Patrol Sgt. Cameron Rhoden.

“We have vehicles all over. Several vehicles tried to swerve off the roadway. We have vehicles that are flipped up on their sides,” Rhoden told KUTV in Salt Lake City. “One of the vehicles was pulling a trailer, and the trailer has pretty much completely been destroyed and is on the freeway.”

Highway I-15 remained partially shut down late Sunday. Kanosh is located 160 miles south of Salt Lake City.
