Five people have been killed and dozens injured after a multiple vehicle crash in Pennsylvania, officials say.
The crash involved a tour bus, two tractor-trailers and passenger vehicles.
Spokesman Carl DeFebo confirmed on Twitter that there had been fatalities but did not say how many people had died or been injured.
He said there would likely be a "prolonged closure" of the road.
The crash happened in Westmoreland County, near Pittsburgh.
The tour bus flipped on its side, DeFebo told The Tribune-Review.
He said National Transportation Safety Board investigators were called to the scene.
