A transit spokesman now says at least eight passengers have been hurt after a truck collided head-on with a Port Authority of Allegheny County bus in Pittsburgh.

Port Authority spokesman Jim Ritchie says the accident happened about 2:15 p.m. Thursday on the city's South Side.

Originally, officials reported only three injuries but that was because emergency crews had yet to examine all the passengers. Ritchie says eight passengers are confirmed as injured and the number could rise, though none are believed to be badly hurt.

Ritchie says the bus driver was not hurt, but that the truck driver has been taken to a hospital with either serious injuries or an illness.

Ritchie says the pickup crossed the center line of the road and hit the front of the bus.
