Japanese tennis star Naomi Osaka has pulled out of a major tennis tournament in New York in a protest over the police shooting of Jacob Blake.
"As a black woman I feel as though there are much more important matters at hand that need immediate attention, rather than watching me play tennis," Osaka wrote on Twitter.
The ATP tournament has now been suspended for Thursday.
Mr Blake, who was black and unarmed, was shot in the back by police.
His shooting on Sunday in Kenosha, Wisconsin, sparked a wave of protests, some of which have turned violent, and a growing boycott by sports stars.
