12:15 a.m.: Reuters reports that Russian-born tennis star Daria Saville, who plays for Australia, says she cannot return to Russia because she spoke publicly against its invasion of Ukraine.

In a social media post, Saville urged Russian President Vladimir Putin to end the conflict and encouraged Russian soldiers to leave Ukraine.

Even though her parents still live in Ukraine, “I can’t really go back,” she said.
