Here's more footage of the storm.
Nick Vertz, a meteorologist with the National Weather Service in Billings, told NYTimes that thunderstorms and strong winds picked up dust and reduced visibility in the area sparked the crash around 1630 local time.
Montana Gov. Greg Gianforte tweeted: "I'm deeply saddened by the news of a mass casualty crash near Hardin. Please join me in prayer to lift up the victims and their loved ones. We're grateful to our first responders for their service."
