A state of emergency has been declared in the U.S. state of Virginia where white nationalists clashed with counter-protesters on Saturday.
A car rammed into the crowds leaving one person dead and nearly 20 others injured.
The suspected driver, a 20-year-old man, is in custody, and the FBI says it will launch a civil rights investigation into the incident.
Two police officers also died when their helicopter crashed as they were monitoring the protests.
The rally, dubbed "Unite the Right," saw hundreds of neo-Nazis, white nationalists and right-wing groups descend on Charlottesville, home to the University of Virginia, to protest the removal of a statue of a southern general from the U.S. Civil War.
Some have criticized President Trump for a delay in his response to the attack.
A few hours afterwards.. he condemned the violence on both sides, though he didn't mention the white nationalists or their views.
