At least seven people were killed Sunday afternoon in a series of crashes involving more than 20 vehicles during a sandstorm, Utah Highway Patrol said.
The crashes happened on Interstate 15 near the town of Kanosh, the agency said in a news release. In addition to the seven fatalities, several people were reportedly taken to hospitals in critical condition. Ground and air ambulances were used to transport crash victims.
A pileup occurred during a period of high winds that caused a dust or sandstorm which reduced visibility, the highway patrol said.
I-15 remained partially shut down late Sunday. Traffic was redirected around the crash site.
Kanosh is located about 160 miles (258 kilometers) south of Salt Lake City.
