(AP) - An emergency official says about 50 to 60 people were injured after car drove into a group of hikers at a parade in a small Virginia town. Washington County director of emergency management Pokey Harris said Saturday that no fatalities have been reported. The injuries ranged from critical to superficial. Three of the victims were flown by helicopter to regional hospitals. Another 12 to 15 were taken by ambulance. The rest were treated at the scene in Damascus, about a half-hour east of Bristol. The status of the driver wasn't released. Multiple witnesses described him as an elderly man. Authorities are still investigating, but Harris says they believe the man might have suffered a medical emergency before the accident.
