Kiwi pop star Lorde blasted race culture in the US, in response to a terror attack on anti-racism protesters at a white supremacist rally in Charlottesville, Virginia.

The 'Perfect Places' hitmaker said the treatment of people of colour in the US was "unnecessary and inappropriate".

It's an issue that has been bubbling to the surface recently, with dozens of unarmed African-Americans slain by US police officers in the past few years, and a rise of white supremacist and "alt-right" views and rallies.

It was after one such rally on Saturday (local time) that cost a protester her life. She was among those run down by a man in a car, while peacefully protesting a white supremacist rally.

"Being a privileged white non-US citizen, I feel like tweeting to reinforce how horrific POC [person of colour] treatment here is unnecessary and inappropriate," Lorde wrote on Twitter after news broke of the attack.

"I just want to say I'm so, so sorry. All white people are responsible for this system's thrive and fall. We have to do better. I'm sorry."

Lorde's message received a mixed response. Some criticised her, while others welcomed her comments with open arms.

"That is a ridiculous statement," user @CharlieR1917 wrote, while @hallepapp said: "This gave me a headache."

But others were more encouraging.

"I love you so much thank you for using your voice to speak up," @thelouvrer wrote.

"I feel the same way. Thank you for saying this and using your platform in the best way possible,' @UGHMELLET said.
