LENHARTSVILLE, Pa. (AP) - One person has died in a crash involving two tractor-trailers and a car on a Pennsylvania highway.

The crash happened around 4:30 a.m. Tuesday and snarled traffic for hours on Interstate 78 in Berks County.

Police say it's unclear if anyone else was injured. Aerial photos show a FedEx truck on its side across the highway.

The westbound lanes remain closed as of 9:30 a.m. and only one eastbound lane is getting by.
