Lewis Hamilton has criticised the Formula 1 community for "staying silent" after the death of American George Floyd, with the six-time champion saying he is "one of the only people of colour yet I stand alone".
Floyd was an unarmed black man who died on May 25 after a white Minneapolis police officer knelt on his neck for more than eight minutes as Floyd told them "I can't breathe".
His death has sparked mass protests across the United States, with governors in several states calling in National Guard troops in an attempt to maintain order.
Several sports stars have called for action to be taken, including England winger Jadon Sancho, who revealed a message calling for "justice" for Floyd after scoring for Borussia Dortmund on Sunday.
Hamilton, the first and only black F1 world champion, has criticised others in the sport for failing to speak up on the issue.
"I see those of you who are staying silent, some of you the biggest of stars yet you stay silent in the midst of injustice," the Mercedes driver wrote on Instagram.
"Not a sign from anybody in my industry which of course is a white-dominated sport. I'm one of the only people of colour there yet I stand alone.
"I would have thought by now you would see why this happens and say something about it but you can't stand alongside us. Just know I know who you are and I see you."
In a second post, Hamilton added: "I do not stand with those looting and burning buildings but those who are protesting peacefully. There can be no peace until our so called leaders make change."
Mercedes have backed their star driver's comments:

F1 drivers: 'Racism needs to be met with action'
Since Hamilton's post, a number of F1 drivers have posted on social media.
Ferrari's Charles Leclerc wrote: "To be completely honest, I felt out of place and uncomfortable sharing my thoughts on social media about the whole situation and this is why I haven't express myself earlier than today. And I was completely wrong.

"I still struggle to find the words to describe the atrocity of some videos I've seen on the internet. Racism needs to be met with actions, not silence. Please be actively participating, engaging and encouraging others to spread awareness. It is our responsibilities to speak out against injustice. Don't remain silent. I stand #BlackLivesMatters."
Leclerc's words were echoed by Williams' George Russell:
