At least three people were killed and several others injured after a blinding snow squall led to a multi-vehicle pileup on an Interstate highway in the US state of Pennsylvania on Monday, according to the Associated Press.
Police said the number of vehicles involved in the collision on the highway ranged between 50 and 60, including trucks, tractor-trailers and cars.
A video posted on YouTube shows vehicles crashing into each other after losing control on the snowy road. Drivers and passengers are seen getting off the interstate as a cascade of crashes unfolds along the hilly route.
Some vehicles also caught fire after the crash, which was later extinguished.
The pileup happened at around 10:30 am on Monday due to the near-zero visibility caused by the snow squall, officials said.
The pileup snarled traffic for several miles on the highway, making it difficult for emergency responders and rescuers to reach the site,
A search and rescue operation is underway and those injured in the crash have been admitted to the hospital for treatment, officials said, adding that this was the second large pileup in a little over a month in Schuylkill County.
The National Weather Service had warned of "numerous brief heavy snow squalls with very poor visibility" in the region.
