A traditional weekend of merriment in a small Virginia mountain town was disrupted Saturday when a man lost control of his car and drove into a crowd of parade participants.

Several people had to be taken to hospitals by ground and air ambulance, but there were no fatalities, police officials in Damascus, Va., told the Los Angeles Times.

About 1,000 people were participating in the yearly parade when the collision took place, around 2 p.m. local time.

The parade was part of Damascus' annual “Trail Days” event. The Appalachian Trail runs through the town of about 900 people, located along the southern border in the western part of the state. Hikers who have used the trail are invited to return to town to participate in the festival, which includes the parade, hiker talent shows and music.

The driver lost control of his car because of a sudden medical emergency, police said. Damascus police and firefighters, along with first responders from throughout Washington County, were on the scene and treated the wounded.

All were reported in stable condition, including the driver. He was believed to be participating in the parade.

Town officials kept the festivities going throughout the afternoon and evening, police said. Officials planned to hold the closing ceremonies on Sunday along with the customary church services at a local park.
