Sixteen-year-old American tennis player Coco Gauff has given an emotional speech at a Black Lives Matter protest saying she "demands change now".
Gauff, one of the sport's rising stars, urged people to vote and speak out against racism, adding: "If you are choosing silence, you are choosing the side of the oppressor."
Protests have been held across the United States and globally since the death of George Floyd in Minneapolis.
Gauff has repeatedly spoken out since.
Speaking in her hometown of Delray Beach, Florida, Gauff said it is "sad" she was protesting against the "same thing" her grandmother did "50-plus years ago".
