One person has died and 19 others were injured when a car rammed a crowd of people opposing a far-right rally in the US state of Virginia, police say.
Earlier, street brawls erupted between white nationalists planning to attend the march and counter-protesters.
The mayor of Charlottesville, where the now-cancelled rally was taking place, said he was “heartbroken” at the death.
President Donald Trump has condemned the violence, and local officials have declared a state of emergency.
The car involved in the ramming incident was later located a few streets away and the driver is in custody, the city’s police chief said.
In addition to those injured there, the Charlottesville Police Department said another 15 people were injured in other violence related to the far-right march.
Late in the afternoon, a Virginia State Police helicopter, crashed in woodland south-west of the city, killing two people; however, there has been no indication that this was related to the violence.
The “Unite the Right” march was called to protest against plans to remove a statue of a general who had fought for the pro-slavery Confederacy during the US Civil War.
‘Car backed up and hit again’
Video posted on social media showed a car ploughing at speed into several slow-moving vehicles, which were surrounded by a densely packed crowd.
A witness said one girl got “tore up” after the car “backed up and hit again”.
Officials said the driver had been taken into custody
