At least three people were killed and several others injured after blinding snow squalls led to a deadly pile-up on a Pennsylvania highway in Schuylkill County on Monday.
Police said the number of vehicles involved in the collision ranged between 50 and 60, including tractor-trailers and cars.
A video posted on YouTube shows vehicles slamming into each other after losing control on the snowy road. Drivers and passengers are seen jumping out of the way as a cascade of crashes unfolds along the hilly route.
A search and rescue operation is underway, officials said, adding that this was the second large pileup in a little over a month in Schuylkill County.
