At least three people were killed Saturday in two crashes each involving 20 or more vehicles each in winter conditions in northwestern Pennsylvania, authorities said.
The fatalities occurred in a crash involving more than 20 vehicles and tractor trailers on westbound Interstate 80 between Clintonville and Emlenton at about 3 p.m. ET, the Venango County Police Department told NBC News. There were at least six injuries. The Pittsburgh Post-Gazette had a lower death toll -- two -- and said whiteout conditions contributed to the accident.
A public information officer at the Grove Medical Center in Slippery Rock told NBC News that another accident involving 40-50 vehicles occurred around noon on Interstate 79. She said about 20 people were treated at the hospital, but all but one were released. The Post-Gazette said the interstate was closed for about three hours after the crash in the southbound lanes in Mercer County.
