ROYERSFORD, Pa. (AP) _ A car crossed a highway median and collided with two oncoming vehicles, killing seven people, including two young children.

``All I saw was a car in the air and those babies ...'' witness Jennifer Hunt said Thursday night. She turned away, unable to continue.

Six people were pronounced dead at the scene on Route 422 near Pottstown in southeastern Pennsylvania. A 1-year-old child was dead on arrival at Pottstown Memorial Medical Center, officials said.

Another young child, age unknown, also was among the dead.

``We've had accidents on this road before but none like this. This is the worst I've seen in 12 years,'' Limerick Township Police Sgt. William Schlichter said.

Police tried to reconstruct the crash this morning. Witnesses said the eastbound car was speeding when it lost control and hit the westbound vehicles. The four-lane highway was closed this morning.

``I was watching TV. I heard a bang,'' said Barbara Pier, who lives near the accident. ``I looked out my living room window and saw a van flipping over.''

Three people were injured, including a 65-year-old woman taken to a Philadelphia hospital. She was reported in critical but stable condition.

Another person was treated and released from the Pottstown hospital, while a third person was in serious condition at the Lehigh Valley Trauma Center.
