Traffic queues after deadly pileup in Montana

Six people have died after a dust storm fueled by wind gusts topping 60 miles per hour caused a pileup on Interstate 90 in Montana, authorities said.

Twenty-one vehicles crashed and Montana Highway Patrol Sgt. Jay Nelson said authorities believe the weather was the cause.

The incident happened 3 miles, west of Hardin. Those storms prompted a severe thunderstorm watch that covered Hardin and other parts of Montana from mid-afternoon until 9 p.m.
