WASHINGTON, Aug. 12 -- At least one person was killed in a multiple car crash following a violent white nationalist rally on Saturday in Charlottesville in Virginia, Charlottesville Mayor Michael Signer said.

"I am heartbroken that a life has been lost here," said Singer on Twitter. "I urge all people of good will, go home."

Charlottesville police said earlier at least three vehicles were involved in the incident. The number of the injured varied from four to 10 in different media reports.

"I'm hearing 9 people hit now. One eyewitness tells me: 'I saw bodies flying'," a netizen called @JDeanSeal tweeted around 2:00 p.m. ET.

Video on social media showed a car at high speed rear-ended another car, then backed up and rammed into pedestrians.

Just before the incident, thousands of white nationalists, neo-Confederates and right-wing protesters, as well as groups that oppose them, clashed during the "Unite the Right" rally at the Emancipation Park in the downtown. Police dispersed the rally after Virginia Governor Terry McAuliffe declared a state of emergency before 11:00 a.m.

U.S. Presidend Donald Trump on Saturday condemned "all that hate stands for" on Twitter in the wake of reports of the violent gathering.
